Excluding the explanation of religion, where did man come from-will this matter remain a mystery forever, or will scientists be able to come up with a cool one?
The questioner probably doesn't research science at all because the arrival of humans is no longer a mystery today, but even a schoolboy can tell you where humans come from.
If you had asked Google once before you asked the question, you would still have found the answer; I did it for you and hold this link: Human evolution
If you do not remember the Wikipedia link, you can also see: Introduction to Human Evolution
And yes, please don't write that evolution is just a 'fictional idea' Science is not religion; There is no business without proof and there is no place for theory without proof Those who do not understand it, whatever they understand, do not understand science
And don't worry, scientific explanations won't make you believe; Instead, be skeptical and look for answers to your questions This is the principle of science
