I feel there is a trap coming....I'll answer anyway.
Can I ask you, do you believe that humankind is the ultimate form of life, the pinnacle of creation (or evolution, for that matter)?
In my belief system, yes, humans are the ultimate goal. At least they are on Earth. God never said to anyone that he had a side project going on in Andromeda or whatever, nor did he say he didn't, so there may be something else there as well.
If my belief system is wrong, then I don't know. If we want to discuss the universe moving forward for another few million/billion years, then I cannot say for sure. At what point will our adaptability through tools and creation overcome our need to evolve? Certain creatures without the ability to use tools have been unchanged for millions of years. It is possible that we have reached a point where our use of technology has made it possible to not need to evolve further.
And if mankind is the end result of a natural progression, where does that place previous taxa which once dominated life on Earth before Mankind existed? Where does it place other animals which exist now (like our closest biological relatives for example)? And what would be your views on what species might (and most likely will) exist in the future once mankind has died out?
Dominant creatures before man are not dominant now, and many are completely extinct. Some just evolved away and others were killed off. Humans have only been on this planet for a few thousand years and we already figured out how to build shelters in all climates, travel in a way that allows food movement and ends foraging and moving with the seasons, and we have looked at different extinction scenarios and contemplated how to stop them, including leaving the planet. In less time we have moved closer to preventing our own extinction than any previously dominant creatures.
Animals that exist with us now, even our closest biological relatives, are limited. If we came from them, then obviously we have moved beyond where they are. Congratulations on using a stick to catch ants. This is my boom stick. Other species that show signs of near-human intelligence, such as dolphins, are physically limited. While their brains may be near ours their physical bodies leave them unable to completely utilize it. Nature left them limited.
If something happened that caused mankind to die out I would have to assume it would stop most life on Earth too, resetting the process. I have hope that before the next ELE happens we will have advanced enough to survive it or prevent it.
I have great hope for humans, whether we were created or an accident of nature. I believe we have done more than anything before us and I hope we will live on to continue to do even more.
