That's merely your opinion, not a validated fact, and you know the military rule about opinions.
If there were such a thing as a time machine, you would find little romance or philosophy in the prehistoric survival-oriented groups.
Their goals would be surviving day-to-day and reproducing to keep the species alive. They had no energy or thought for anything else, and no food to spare for idle occupations.
Your maudlin wanderings are the result of a lifetime lived in a standard of luxury and ease far beyond the wildest and most feverish dreams of paleolithic peoples. You have already out-lived the oldest paleo-humans by a wide margin, simply because of the advantages of your advanced lifestyle. If you were back in the Paleolithic, mindlessly fantasizing about the rocks and trees, you would be dead by thirty at the latest, and that would be OLD by the standards of that time. No drugs or tiswin, either.
As for the age remarks you constantly make, I'll outlive you.
