We exist at what may be the earliest possible time for life such as us to exist.
Well, that's a glass 2/3 full kind of view, vs the glass being 1/3 empty, which blows my mind.
What have we been doing for the last 13 billion years? Sitting around not existing, waiting for some panspermia-bent mega-civilization to seed the area?
No need IMO - it's just the environs that change; species tend not to last billions or even millions of years, but I figure that anywhere in the universe that is not totally inimical to life, there is already life and it is evolving. Our sun is a third generation star, and the chances that the human species will be the one to survive its demise, is charming but silly. Our atoms will mostly scatter into a cloud of gas or be torn apart by black holes, some to re-form into fourth generation stars which may have planets that evolve intelligent life forms that make plans to survive to inhabit the fifth generation solar system ...
I'm really not going to miss those atoms of my body, if any, that get sucked into black holes. Other than that,
I'LL BE BACK! It's just going to take a few.
