What makes you think that there were no human like creatures prior to Adam?
Genesis 1.
Geologists think they've found some.
They believe man existed before man existed? That's clever.
God created animals and then created humans.
Satan had already been kicked out of heaven.
Agreed.
Some (me) believe that he was the light of the pre-Adam creation, hence his original name Lucifer.
Lucifer was an angel and his name means "light" or maybe "light-bearer".
But he wanted to be greater than God, tried to overthrow him and got thrown out of heaven. All the angels who had joined in the rebellion were thrown out too.
All I'm saying is that there is a plausible way to reconcile the fossil record and the Genesis account.
I didn't even mention the fossil record.
Genesis 6 tells us that God sent the flood because the wickedness of the world had become too great - there were people already in the world, who had forgotten God and were sinning.
Jesus said that his return would be as it was in the days of Noah; people eating, drinking and practising wickedness and then judgement would come.
Before Adam and Eve fell, there was no sin in the world, therefore no need for a flood.
I was spared the incessant bombardment of evolutionary theory turned "fact". I was taught both creation and evolution at the secular school I attended. Evolution made no more sense to me then than it does now, and I was not born again at that time. A lot of Christians struggle with Genesis. It is not necessary.
I wasn't talking about evolution, I was talking about Genesis.
Genesis 1 says that God created the universe, making animals and humans on the 6th day.
Genesis 3 says that Adam and Eve disobeyed God and then sin came into the world - Cain killed Abel, and the more people increased in numbers, the more sin grew, Genesis 6:5-6. God sent the flood because of all the sin on the earth.
This is the order of things in Genesis; creation, fall, flood. The flood was not before the fall because there was no sin to wipe out.
