I once watched a video in astronomy about aliens. Except the aliens were just single cell organisms. We discussed how those cells could evolve into bigger life and such. Some people thought that they shouldnt count as life forms.
How would you define life?
A single cell is absolutely life. In fact I predict that there are microbes on at least one, if not more, of the moons in our Solar System. Europa and Titan are two big contenders. However I also see no reason why "intelligent" life can't exist elsewhere. I put "intelligent" in quotations marks but since we are the only known planet for life we can't have an accurate description of intelligence. It's very possible that there are life forms so intelligent that they know of our existence and simply don't care. We could be the ants of the universe. But there could also be just average multicellular evolved life. Though we probably won't find any of the same creatures we find on Earth because evolution is so heavily dependent on the habitat that they're from, we will most likely find similar creatures. It's also a matter of if they are DNA based.
I used the words could and probably a lot in this bit only because there is no real proof. But know that I whole heartedly believe that everything I said exist. However the extremely intelligent life that knows about us is iffy. But hey. Why not!
"We are star stuff."
I definitely agree! With all of that actually. My biology teacher always said that "cells are the building blocks of life." Without them, where would we be?
We are not the only life on this planet.
But also, yes. There is life on at least one other planet.
The word "we" in this post is kind of vague. It could be speaking for all humans, all amirite users, OP plus the person reading the post, or all life on earth.
you would know because you're an astronaut
I wish more than anything else for that comment to be true.
I agree. There are dogs, cats, horses etc
