I went over to Andromeda and one of the first stars that I clicked had life and when I checked it out, I saw that it was extremely young, fresh out of the oven so to speak.
While there are hints on Earth and I agree that life got started very early on, within a couple hundred million years, but this one is so young that it would either have proto-life or the ancestors at the deepest roots, no, the deepest root tips of this planets tree of life.
There is also an oceania with life on it that's around the next gas giant in, and it just happened to be eclipsed by the gas giant at that moment.
Edit: I just found another system (a binary) nearby that's 244.5 million years old, no life in this system though.
Edit3: It seems like there are a lot of very young stars out on the rim of the galaxy (shouldn't they be in the spiral arms?) because I just found one that's 44 million years old, and theres a 44 million year old White Dwarf, which is plausible, but BOTH of the stars being 44 million years old?
I disabled the clouds since they blocked the moon there anyway.
