Potencial Alien Lifeforms

I often think about what kind of alien life could be out there.

A lot of us, when thinking about intelligent alien lifeforms, think of something humanoid like, with thumbs and two legs and such. But as far we know, aliens could look like cows! Or they could be more similar to crabs (because on Earth, life loves to evolve into crabs for some reason lol) The possibilities are endless!!

They could communicate with colors, or with thoughts! Maybe they dance like bees to talk. They could be as small as a bug, as big as the Mount Everest. They could be made out of gas, or flesh, like we are. HECK!! There could be lifeforms that don't even live on planets!!! AAAAAAAAAAA
