In the beginning God created

Science claim that in our evolutionary process we were hunter-gatherers who hunted game and collected plant foods (called foraging) rather than grow or tend crops. Hunter gatherers is the term used by anthropologists to describe a specific kind of lifestyle, that of all human beings until the invention of agriculture about 8000 years ago.

Mommie, where did we come from? Son, we are just a figment of evolutionary scientists imagination.

Once I was nothing in a pool of primordial mud,
then along came a bolt of lightning, now I am a slug,
then I became a monkey and climbed up a tree,
when I came down, I was a professor with a PHD

Then God said, “Let us make man in our image, after our likeness. And let them have dominion over the fish of the sea and over the birds of the heavens and over the livestock and over all the earth and over every creeping thing that creeps on the earth.” So God created man in his own image, in the image of God he created him; male and female he created them.
 (Genesis 1:26-27 ESV)
The LORD God took the man (Adam) and put him in the garden of Eden to work it and keep it.(Genesis 2:15 ESV)

Now Adam knew Eve his wife, and she conceived and bore Cain, saying, “I have gotten a man with the help of the LORD.” And again, she bore his brother Abel. Now Abel was a keeper of sheep, and Cain a worker of the ground. (Genesis 4:1-2 ESV)

Cain knew his wife, and she conceived and bore Enoch. When he built a city, he called the name of the city after the name of his son, Enoch. To Enoch was born Irad, and Irad fathered Mehujael, and Mehujael fathered Methushael, and Methushael fathered Lamech. And Lamech took two wives. The name of the one was Adah, and the name of the other Zillah. Adah bore Jabal; he was the father of those who dwell in tents and have livestock. His brother's name was Jubal; he was the father of all those who play the lyre and pipe. Zillah also bore Tubal-cain; he was the forger of all instruments of bronze and iron. The sister of Tubal-cain was Naamah.
(Genesis 4:17-22 ESV)

 
When man began to multiply on the face of the land and daughters were born to them, the sons of God saw that the daughters of man were attractive. And they took as their wives any they chose.
(Genesis 6:1-2 ESV)

The first humans were very intelligent. They were very knowledgeable in all things. Some lived in cities, some in tents or on farms. Because of the closeness with their Creator their life spans were almost 1000 years. Music was important in their lives. The effects of sin would slowly alter mankind's life.

Cave dwelling didn't mean that our ancestors were neanderthals. A few people have always lived in caves right up to our present era.
