Just like us - Neanderthal children grew and were weaned similar to us:

Hi Mark
This is a very thoughtful response. Thanks.

What seems to me to be the case is that God provided to the earth with what is in Genesis 1-3. That appears to be the starting point of science. By science I mean creating hypotheses that can be tested. The hypotheses may include creating predictive models such as Newton’s model of Gravity or Maxwells model of electro magnetism. These models help us understand what God has provided.

It is fascinating to me what was given by God to the Israelites in the Torah which was beyond current human knowledge such as the concept of “clean animals” in Leviticus.
