When did humans stop living in caves and start building houses?

They never lived in caves as a complete race. Some people lived in caves as so do today - Gran Canaria for example. Atheists and scientists would like us to believe that man was a hunter/gatherer for a million if not hundred of thousands of years. This is not so. Why would a man walk miles to hunt for meat or vegetables when it would have been much easier to heard animals and breed them or plant vegetables where he lived - right outside the cave for some, lol. Is it only in the last few thousand years of existence that it has dawned on man that he can farm. I don't think so.
