We don't even understand all of what we need to know
as to how life was allowed to evolve here. For instance our magnetic field.
We know we would have lost a good portion of our atmosphere without it and it helps to protect living things on the ground, but what other effects does it have on the air we have, to allow us to live in the first place? Without that magnetic field, what would out atmosphere look like? Another Venus?
All this talk about finding another Earth is BS. The list needed to make another planet, an inhabitable earth, is long and we do not understand how long that list has to be.
So stop already trying to tell us we found another earth. No, we haven't. We found another rocky planet, in the Goldilocks zone. Normally it's within 50% larger that the size of our own planet. A real another Earth would have to be with in a few percent of everything of our own planet. Sunlight, gravity, magnetic field, water, minerals/metals required for life, etc.
And even if we did find one, there is no guarantee of any kind that there is any life more intelligent than say, goldfish there. No matter the age of that planet. "Intelligent life" may be a fluke of this planet alone. At least until Mother Earth finishes correcting her mistake.
