The reason why humans cannot control Bitcoin is determined by the Bitcoin technology itself. Bitcoin's quadratic elliptic curve encryption, and the mining packaging with verification system established in human society, has formed an immune system against humans. Humans’ existing science and technology cannot crack the private key, nor can they successfully attack the entire package verification system. Humans cannot influence the work of the Bitcoin system.

But in Bitcoin, humanity has lost their power.
Lol, what a load of...
If humans would want to completely destroy bitcoin they would simply stop using it, if nobody mines it, nobody uses it, bitcoin is dead.
Actually, in reality, it's a bunch of humans that keep bitcoin alive, without them there would be no nodes, no mining, no usage, in short, no bitcoin.
And one more thing, bitcoin was created by humans, it is getting its code updated by humans, the segwit was activated because humans wished so, the taproot lock-on happened also because humans wished for it.
The Bitcoin ledger can still exist after net split, and even if there is a world war between humans, the Bitcoin ledger will still exist. Even if all the Bitcoin mining machines are destroyed and most humans go extinct, the Bitcoin ledger will still exist as long as there are two earthlings with two USB flash drives.
Probably you don't understand what extinction means. Also, I doubt the two surviving earthlings would rush to rebuild the bitcoin network as the first priority unless they own all the coins at that time. What would you do, strat with the old chain with all the lost coins or with a brand new one when you're satoshi?
