The Dinosaurs were long gone by the time Adam walked the earth. In fact Adam was not the first man, only the first of us.
The Bible does give a little glimpse into the gap between Gen 1:1 and Gen 1:2, but you have to look to the prophets to find it, not in Genesis.
Sin (death, sickness, etc.) came into the world because of the Garden of Eve sin. Because of this, God sent his son, Jesus, to redeem the world (not only man, but earth).
If sickness, death (i.e., fossils) existed before man and man's "sin" (i.e., the so-called 'gap' between Gensis 1 and 2) it cheapens the sacrifice Christ made on the cross. Who can then redeem the world?
Jesus must have been wrong when speaking on Adam and Eve.
Mat 19:4-5
4 And he answered and said unto them, Have ye not read, that he which made [them] at the beginning made them male and female,
5 And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?
In case anyone wonders the passages Jesus is quoting:
Gen 1:27
27 So God created man in his [own] image, in the image of God created he him; male and female created he them.
And:
Gen 2:24
24 Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.
For the intellectually honest, you will also note that Jesus added the qualifying words "at the beginning" to avoid any potential misrepresentation.
If you look at the savage intent of dinosaurs in the art of survival...man never stood a chance until the vast numbers of dinos died off. The human race had a chance to build and grow at that point...and mental evolution (my preferred term for it) started to occur. Man learned to adapt and survive, and to travel vast stretches of territory. This whole terms of evolution and creation fail to address 1000s of variables in society, culture and the earth itself.
what do the prophets have to say about the gap between Gen 1:1 and Gen 1.2 ?
