A BBC News article dated August 19, 2015 says that evidence from a variety of sources suggests that early humans were much more sophisticated than we could have imagined.

Here we go again. More and more discoveries are proving evolutionary theories wrong. The first humans were much more complex than they imagined. That is just what the Bible said about our early ancestors all along. For example, the very earliest humans mentioned in Genesis:

• Composed poetry (Genesis 2:23; Genesis 4:23-24)
• Built cities (Genesis 4:17)
• Lived domestically (Genesis 4:20)
• Raised livestock (Genesis 4:20)
• Developed musical instruments and could play them (Genesis 4:21)
• Forged various metallic tools (Genesis 4:22)

The Bible, being ahead of its time, once again trumps evolutionary scientists and their theories about our early ancestors.
