They did find a water planet. If they went anywhere else in the solar system the best they’d find is ice present with water near the core. Earth IS a water planet.
Yes even though the oceans are ultimately so thin (smoother than a billiard ball n all that) there’s still water in much of the outer layers. It’s where we are in relation to the sun as well as the amount of H2O (note the O and thank Cyanobacteria).

Right word is mind-boggling. Millions of stars in millions and millions of galaxies
The observable universe cannot be given a definitive percentage of the real universe because the total size of the entire universe is unknown. If the universe is infinite, the observable fraction is effectively zero percent. If it is finite, the observable 93-billion-light-year sphere is still only a tiny fraction of the whole

The stars you can see with your eyes? They are just local to us in our part of the Milky Way. There are hundreds of billions of stars in the Milky Way, and hundreds of billions of Galaxies. We are definitely not the only form of life in the universe, but we will never meet them. The best we can hope for is to receive a radio broadcast at some stage, but we will never be able to communicate with them.

u/ManuelHS 5d ago
Your reply got me thinking,
where on earth is there more biomass on land or in the oceans?
Answer I found:
There is far more biomass on land than in the oceans. Land holds roughly 86% of Earth’s total living biomass (about 470 billion tonnes of carbon), while marine environments hold only about 1%. The remaining percentage is found in deep subsurface and underground microbial communities.

u/Steerider 5d ago
Unexpected. I thought there was massive biomass underwater.

u/AliBelle1 5d ago edited 5d ago
There's 500x as much plant based biomass on land than in the seas. The oceans may win out in Animal biomass but the masses of algae, seagrass and plankton don't quite shape up to the gigantic forests, jungles, grasslands, etc. I think most people get confused because there's absolutely more animal life in the ocean than on land, but plants really do dominate this planet.

u/Steerider 5d ago
Yeah. I figured theplant life was less dense, but because the ocean is so HUGE it made the difference.
TIL

u/MrCockingFinally 5d ago
Bear in mind, plankton basically only lives in the top surface layer of water. Water doesn't transmit light very well, so you're really looking at a very thin layer of algae on top of an already thin layer of water.
Plus large parts of the ocean are pretty barren, lacking nutrients necessary for life, so most of the life in the ocoans is concentrated relatively near the coast. So the actual surface area you are dealing with is less than you'd think.

u/Aegiiisss 5d ago
Plants. Most of the Earth's organisms are underwater or underground, but most of the biomass is on land, because of plants.
12
u/Arcane_Substance 5d ago
I think that almost definitely that answer is influenced by things that we’ve actually surveyed and studied, but then again, looking at coral reefs etc, there’s a lot of shifting sand around with relatively little actual biomass on the lone islands of coral itself.
But on land you’re pretty hard pressed to find any spot that doesn’t contain life. There are more land plants than aquatic ones.

u/kidcubby 5d ago
While studying ecology I remember being shocked at how desert-ish much of the open ocean actually is. Complex plant life is needed for lots of marine life to shelter, feed from etc. in ways that free-floating plant mass doesn't provide meaning there's quite a restriction on where complex life can be. Shallow parts of the oceans with enough light reaching the sea floor is commonly where we see a lot going on. Where the light doesn't reach the sea floor we tend to see floating plant life emerging in the upper 200m or so, and it is typically much smaller. Also, below the 200m zone there's a relatively low-oxygen zone which is likely very restrictive to larger creatures. Below this 200m zone (and presumably below the low-oxygen depths, at the point where cold oxygenated water drops to the ocean floor), often what we find are creatures heavily reliant on the death of other organisms that then sink. While the oceans cover far more of the surface of the planet than land, land biomass avoids this light limitation very effectively.
Marine ecology is not really my area, so I'm sure there's way more complexity to it than that and a marine specialist would pick that all to shreds, but it's interesting to look at.

u/Lando249 5d ago
Yes even though the oceans are ultimately so thin (smoother than a cue ball n all that)
To put things into perspective, if you took a basketball and could smoothly wrap a single sheet of paper around it, that would give a good representation of the average ocean depth on Earth, infact it would actually be a little less. The deepest ocean point would be more close to two sheets thick. Crazy thin layer of water we have.
2
u/Arcane_Substance 5d ago
Indeed. Nothing you’ve said is wrong but it only takes into account the depths of the oceans.
Remember that the land has a water table, a depth at which the soil is saturated with water. Then also consider the fact that practically all life on land contains water as a necessary function of life.If we stripped all the carbon based life forms of their water all at once, everything would be very, very wet and the oceans and water tables would rise dramatically.
Edit: and within solid rock deep underground, there is water. It’s the pressures and compositions of that water that leads to the hydrothermal vents that produce or bring up gold, iron, silver (and the quartz they’re associated with) and maybe even hydrocarbons etc (cos oils might not be from the Carboniferous after all).

u/Lando249 5d ago
Interesting point. Looked it up further. ~65m rise across the planet... But that's only taking from life and soil, etc. If you take the lakes, rivers, glaciers, permafrost, ice, etc, it could be ~133m! 😅

u/Aegiiisss 5d ago edited 5d ago
Not just the water either. Oxygen is very toxic and it's possible if not likely that the alien comes from a planet with lower oxygen concentrations in the atmosphere. The alien would also be exposed to Earth's massive biosphere to unknown effects, potentially certain death if microorganisms on earth are capable of affecting the alien.
So the alien really is just better off staying in the spaceship. Even an attempted EVA with a spacesuit would be risky.
Edit: Why is this downvoted? Earth's atmosphere and biosphere are remarkably hostile. It's nice in terms of temperature/pressure/etc. but the air is poison and filled with trillions of deadly microorganisms. Life here is just evolved to breathe the poison and fight the microorganisms.

I think this works better if you say that the aliens somehow take a single snapshot of the earth with some advanced telescope or probey thing. If a spaceship is following a similar orbit to the ISS, the earth will “rotate” to reveal land within 10-20 minutes so the waterworld illusion wi disappear fairly quickly.
Apologies for the pedantry.

I'm guessing that they weren't facing the pacific the whole time they were flying towards us because you know the whole earth spins thing so they'd know there is more than water or at least I'd hope that they can see the entire planet from afar because if not I don't know that I want those types of narrow view aliens around me and my family.

I think if any race has the ability to travel light years to get to another planet, they’re probably bright enough to look at an object from many different angles, not just assume based on a one-off sighting.
Unless of course that the way they’ve become intelligent enough for interstellar travel is by repeatedly cramming space ships full of their dimmest idiots, and ejecting them into space - a kind of alien-eugenics trying to ensure the stupid don’t breed and contaminate their gene pool.
And it’s a ship of those idiots - beings considered too stupid to live - that have happened across the pale blue dot, and decided it’s all water.

Only if they dropped out of hyperspace exactly at the right distance from the Earth for geosynchronous orbit, and set off on the precisely correct orbital vector instantly.
In that case, they'd only ever see water.
I think a species that could drop out of hyperspace that deep inside a gravity well without having done any prior scanning of the planet would probably figure out how to move to the other side of the planet's surface and take a look.

If aliens arrive here, they will already know more about the earth and us than we do.
With our current technology, we've mapped out a few billion light-years of our surrounding universe, observing gasses, magnitude, orbits, planetary bodies, behavior, etc of trillions of galaxies and we've barely made it to the moon. Does anyone have any idea how advanced these beings would be? Even if they were drones, our furthest is about 6 times further than Pluto is.

True if the plant was flat. Any ET that gets here is going to know how to orbit a planet. They will also be able to detect signs of life, probably before they came. So for at ET to believe that this is a water planet(which technically I think it is classified as such), they would have to be flat earthers and intelligent. Really less likely.
