Hey Veeky Forums, question:

Kej'd :D

I guess this kind of answers my question
here

So then they evolve into land species or amphimbians, and thus not the the original question of OP

You air breathers are really full of prejudice.
Fuck you guys and your air.

Meaning no atmosphere comparable to ours, meaning the liquid gets frozen or boiled away meaning no civilization.

If we can fire in space then we can fire in water.

Besides, stage 1 can initially use water to launch into the air before stage 2 starts and uses fire.

No, being smart enough to use fire is what allowed us to increase standard of living so we had more time to get smarter. Other animals have experienced fire without turning intelligent. We had the capacity for intelligence before we used fire, fire just gave us the circumstance to exploit our capacity to learn.

So because we CAN put people underwater or in outer space, we're evolving into non-land mammals?

Also, what about crabs? They're aquatic animals that can live out of water. They could live on an ocean planet, and could work in 'dry' habitats if they could construct them.
