Ok so I know that currently NASA have began work in this field. And that there have been specimens on earth(inconclusive ones though) but i just want to know. Could we possibly determine an aliens biology using our own. Would they have roughly followed the same laws of evolution as us(assuming the planet is a twin earth) or would they follow a completely different path such as cloud like figures that have electricity surging within them and this gives them consciousness?
Your opinions
I am aware I was quite vauge there but I really want to learn off the replies so please reply with your thoughts
