Of course over very long (of unknown length) it's not unreasonable to suppose the effects of consciousness might be the root. There is a strange observer effect in many things, so why not distant galaxies?
I agree; I take the view that consciousness is everything.
So what about the following as some sort of thought experiment?
There is a ‘big fella’ consciousness out there that needs to colonise as many places in the universe as possible to survive. Probably he (it) has to lay claim to as many habitable exoplanets as possible so as to keep other ‘big fella’ beings off his territory. So when he (it) sends out his little fellas (us) to colonise new territory he wants them to evolve more and more consciousnesses and claim more and more territory throughout the greater universe. So when us little fellas build something (as a result of our developing consciousness) the ‘big fellas’ make sure there is a duplicate built on another part of the universe. Just a safety measure – never know we might blow ourselves up and all that hard work might be lost.
And of course the ‘big fellas’ have little fellas evolving ever greater consciousnesses on other habitable exoplanets in other places throughout the universe – building pyramids and things. So how does the ‘big fellas’ make sure all these other discoveries, throughout the greater universe, do not get lost? He (it) makes sure there are copies of the pyramids and things built on other exoplanets (earth).
Thus explaining why we cannot find the tools.
