How old is the first man?
First man
It is a controversial matter. No one really knows that answer. But scientists have a general idea. Though it depends on what kind of science and what religious backround or cultural preferences; it's somewhat agreed that humans first appeared about 3-8 million years ago. I believe that we appeared sometime in the past, say 15,000-20,000 or somewhere near, definitely not in the millions. But even scientists argue among themselves, so it's something that we need to let go. No matter what evidence is provided, we still will not come to a single, popular, unanimous decision.
If you are arguing from a religious perspective, it depends on what your religion says. If you are asking about the first homo sapiens, then it was definitely closer to a million years ago or more (I can't say for certain). If you are asking for the first civilized man, then it would be somewhere in the range of 50,000 to 20,000 years ago. First widespread use of agricultural and domestication shows up around 40,000 to 30,000 years ago. And language and religion appears a little bit later than that. Civilized burial and cremation appears a little bit before agriculture, and established permanent cities appear around the same time.
So you're looking at a variety of responses depending on what you classify as "the first man."
