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?

When was Lucifer created and when did he fall?
You probably mean Adam and Eve's sin in the Garden of Eden.
Evidently that wasn't the first time sin had been rampant in the world, however. If you would like to have a discussion about it, please FReepmail me.
