Obviously, in a hypothetical scenario like this, evolutionary theory would take the biggest hit.
We'd have to rethink what "life" even means in any form. Just the idea that two separate evolutionary paths exist in the universe would trigger massive questions:
Is there just one single evolution spanning the entire cosmos where we’re just a tiny fraction, or are there multiple, distinct evolutions? If it's the former, it gives massive ammunition to anyone claiming life didn't start on Earth but came from deep space.
On the flip side, if there are separate evolutions, comparing them would be fascinating. Do they share common elements—universal laws that hold true regardless of the planet or star system they emerge in?
Even if nothing else, we'd know our own evolution isn't just some isolated quirk of complex matter, but something non-local that relates to the whole universe.
Plus, this would absolutely wreck any philosophical theories built around humans—basically, anthropocentrism. Creationism would definitely be called into question, and there's a huge chance we'd approach religious concepts from a completely different angle.
God, who would now have to account for another intelligence, wouldn't be served by traditional rituals and prayers anymore, nor would those things feel like an obligation for a "true believer."
The same goes for fundamental philosophical problems like existence, being, ethics, or the source of morality (looking at you, Kant). We’d likely pivot toward totally unexpected perspectives. I can't even imagine what happens when you mix our way of thinking with the culture of a consciousness that developed entirely apart from us.
Then there's the question of whether such a being—one capable of interstellar travel and advanced tech—must have its own versions of law, morality, politics, and economics, or if those concepts are strictly human constructs.
And of course, there's the physical form of alien life. I'm not talking about looks, since we don't know that, but rather their social structure. They might exist as a collective instead of individuals like us, or maybe they aren't social beings at all and live as solitary units. Something along the lines of the creatures described in Vernor Vinge's "fire above the depths," where a single individual actually consists of four to six physically separate entities.
Just throwing ideas out there. We could dive deeper into any of these if you guys are interested.
