You can stop speculating. The structure of matter is uniquely fine tuned for life. Change any aspect of it and the universe could be created the exact same improbable way and would be devoid of life. There aren't an infinite number of ways life can exist and evolve into intelligent beings. If there are other intelligent beings out there, they will be more similar to us than different to us. And would have evolved in a similar fashion.I have no idea…I’m just speculating. Everyone seems convinced that the conditions that happened here are the only ones that could have ever produced life, I’m saying, how do we know? Why couldn’t there have been other planets that underwent other conditions that life had to adapt to, in their own way? Again, WE only came to be because we adapted to our own conditions, and it took (according to evolution), only 2 million years?
The universe is a really old place, why couldn’t there have been evolution happening on other planets across the universe?
