Question

I have a question for the Rabbi.
Evolution created millions of years during which there were human beings who lived out entire lives. By contrast, the Torah was given only about 3,000 years ago.
 
My understanding of this is that the Holy One, blessed be He, created His world through a natural process, and that’s simply how it works.
The question is whether that doesn’t make the lives of all the people who lived before the giving of the Torah somewhat unnecessary on a massive scale.
They didn’t even have anything on the basis of which to receive reward, let alone meaning or even any kind of faith / belief (they weren’t wise enough to believe).
Can one really say this absurd thing about those human lives—that technically, most of the time there has been no Torah in the world rather than Torah in the world?
After all, again, that turns their lives into something unnecessary from a Jewish perspective… and it’s very easy to say they lacked spiritual meaning, but what if it had been us?
 
Thank you very much!
