It is said that, creation and the making of Adam and Eve happened at the same time.
The date when Adam and Eve were made happened at 4004 BC which was the year worked out by scholar’s Archbishop Ussher, Rabbi Yossi also worked a date but Rabbi Yossi makes the date 3760BC.
These dates have been worked out be studying the Bible and using genealogy which i’m sure took many years.

No matter which date it is, because there’s only 240 years in it, is it right that man never set foot on earth until Adam and Eve were made.
Humans were on earth long before the dates above, all beit in a more primitive form until evolution kicked in.

Homo Erectus is the closest being that you could call human and the first to make crude tools and axes.
The first body found was carbon tested and dated back to 1.6 million years BC. there were bodies dated long before this as far back as 4 million BC but they did not look human, so through evolution they evolved into humans.
