Shalom and thank you for your question! You wish to know if you as a Jew ‘should ‘ accept ‘Torah miShamayim’, and I think what you are asking is: Should you believe in Torah as a Divine gift, the word of an omnipotent G-d?
Yes.
Why?
Actually I take it back. It is not a matter of ‘should’. That is, it is not that you are being forced by anyone (outside of your own soul, which is a part of G-d above and yearns to reconnect with G-d.) In this world there is free choice, which is why good people can suffer and bad people can have it good. At least, that’s how it looks to us. Because we have free choice, we can choose to ignore the Torah. That is kind of a shame, because, as the Sages of the Talmud teach us, the Torah is the ‘blueprint’ by which G-d created the world. Just like our washing machine comes with instructions, the world comes with an instruction manual that is designed to help us navigate the challenges of this world.
A serious student of history will see that societies over the centuries have vacillated from being decadent and overly liberal, disrespecting the concept of family values and loyalty, to become overly puritan or dictatorial or terrorist (in the name of ‘morality’) and crusading their warped values in an attempt to force others to hold them. Where is the balance?
(In truth the world has come a long way but we have to be careful not to lose sight of the goals in an attempt to be egalitarian.)
If you are doubting whether Torah and science contradict each other or not, there are many Jewish scientists who practice Judaism and not only do not see any contradiction between Torah and science, they have written books and articles to that effect, based on their knowledge in both fields. One such person is the Professor Herman Branover, who pioneeed work in the field of hydrodynamics. You can look up his works, such as the magazine B’Or ha’Torah, which includes contributions by many people in the field of science.
If the question is, was the Torah itself given by G-d or did people make it up? We read secular history books unquestioningly. We respect historians. Who are they? People. People who read and researched what other people wrote. The Torah was given at Sinai to thousands of people, who passed it on to successive generations. For thousands of years, Jews have kept the same basic laws whether they lived in England, Europe, North Africa, or Israel. Why would this be less reliable than any history book?
If you came across an intricate picture with many details lying on a desk near an old-fashioned ink well, would you believe that a cat had jumped on to the desk, upsetting the ink well and thus causing the intricate picture to be formed on the paper? In the same way, the world did not come about as a random ‘big bang’.
Imagine now, that you are in a supermarket, and suddenly on your way out, you overhear a loud conversation that sounds rather dramatic and threatening. Concerned, you glance in the direction the voices are coming from, and you wonder if help is needed. Only a couple of seconds later do you perceive the cameras focused on the people carrying on the conversation. You then realize that a movie is being filmed on the premises. I experienced this scenario two weeks ago! So, not everything we see in life is as it appears to be. It can be that when a person LIVES a Torah lifestyle, an understanding can be gained which makes some of the questions fall away. When you are looking in from the outside, you may see people speaking but not be able to hear them. You then have no idea why they are laughing or crying! It is true that some people leave a Torah lifestyle, while on the other hand, others from secular backgrounds CHOOSE a Torah lifestyle. Again, the world was set up in a way that enables free choice…
As for the questions that do not fall away when a person lives a Torah lifestyle, that is a healthy situation. G-d is infinite, and as such we can only strive to understand His wisdom, since we are finite beings. The Torah encourages us indeed to ask questions and continually strive to learn and understand more about G-dliness. When the Jewish people received the Torah, they said ‘Na’ase v’Nishma,’ we will DO and we will hear…’ The word DO here refers to keeping the Mitzvot, the commandments, while the word HEAR refers to understanding. The Lubavitcher Rebbe explains that keeping the Mitzvot precedes understanding them and also helps it. (The Letter and the Spirit, p. 267-8.)
All of us daily must attune ourselves to the inherent spirituality we have and utilize our free choice to choose life, as it is written in Deuteronomy 30:19, “Behold I have placed before you…life and death…blessing and curse…and you shall choose life.”
