Let’s go through several issues.
Just imagined I’d return from a lecture by Prof. Einstein. He just clarified his Relativity Theory to me and I got it. And then you ask me: Was he wearing a tie? That’s not an evil question. But it’s utterly irrelevant.
G^d tells us how he created the Universe, humans included. And then you ask: Did it happen like that? That is so irrelevant. He doesn’t teach what happened. He’s teaching morality which is (kind of) beyond science. If He wanted us to know what happened, He’d say: study history, psychology, science, and the philosophy of science, eat your greens, and notice your findings, and you might figure it out. (Evil is an overall excess of pain.)
Problem is that by the time we will begin to figure out morality from life and science, we’re probably 90 years old. And then it’s often hard to be flexible enough to implement our findings while we’re only beginning to understand it. So, as long as we haven’t stopped death, we need a ton of truth, wisdom, and morality to assist us to lead us toward a moral life.
Meanwhile, doctors are racing toward understanding, healing, and then preventing all major illnesses, aging, and ‘natural’ death itself. That won’t help a lot if we’d still murder ourselves (addictions) and murder others (hatred, selfishness, jealousy, supremacy, nationalism, etc.).
So, G^d gives us a preview of what we’d conclude at our 300th birthday. He’s not possessive or controlling about it. If you’d prefer another moral compilation to help you gain morals as days go by, so be it. Only, after we proved that we couldn’t handle His advice, He picked one People to teach everyone. If you’re Jewish, follow the Jewish script. You’ll see: good stuff.
However, we need teachers to help us decipher the Torah, Talmud, and later writings. They must be more than honest, smart, and nice. They must be all-round moral. You can’t learn ethics from an immoral person. If they had very moral parents and teachers, they could get there faster. But, even such a life doesn’t leave a person unchallenged. We each have our struggles to become all-round ethical.
And even when we find such teachers, if they speak a language we don’t, we depend on the honesty, smartness, wisdom, and level of morality of their interpreters.
And if they are not alive anymore, we need to rely on the ethical fitness of their editors and publishers.
We don’t need a twist of immorality from ourselves, or our teachers, or their interpreters, or their publishers. We need our own brains to tell the difference between truth and fake. Being very honest is the first step.
We have no second to lose. We must become more moral or we make the whole quest for immortality useless. What use is it to be able to prevent and cure all illnesses and aging when we just kill each other off at unprecedented efficiency?
You can soothe yourself with some idea that life and death belong together, that the goal of life is to die, that it’s meant to be or is natural. I never bought that. And I’ll tell you more: Quintessential progress will not come from people who believe that kind of pacifiers.
