“Why did it take so many years from creation for Judaism to develop as well as other monotheistic religions? How come idolatrous religions are still alive and strong even in this age of understanding?”
I am not privy to Hashem’s reasons for the timing of when He gave the Torah, though there are various factors that are discussed. And who says that this is an age of (religious) understanding?
“Obviously there are many instances where modern medicine is not fit to cure and more homeopathic and herbal remedies are necessary and can fix. Wouldn’t it be strange if Judaism doesn’t have those essential secrets but having to rely on other religious wisdom?”
Who says all wisdom is religious wisdom? We are allowed to utilize non-religious wisdom that comes from the nations around us, such as technology or medicinal cures.
