what a load of christianity
Whatever method of dating you use carbon or RD they are ONLY THEORIES PRESENTED AS FACTS, which inherently make them unprovable. Unless you have the KNOWN facts of the environment at THAT time it is impossible to STATE 100% this thing is 100 million years old.
OK, maybe not exactly 100 million years old... more like "between 90 and 110 million years old" - nobody claims infallibility. Also, the age of many discoveries is being revised continuously as methods of calculating them changes.
Incidentally, one thing we can say with absolute certainty is that the universe is far, far older than 100 million years old. We know the speed of light accurately (certainly in our local universe) and two simple, provable techniques (trigonometry using the diameter of Earth's orbit as a baseline and redshift of the light reaching Earth) give very accurate locations of at least the closer stars and galaxies. Combining these gives an irrefutable minimum age of our universe of at least a couple of billion years (I haven't gone back any further than this in case key properties of the universe such as the speed of light change outside our local region).
If dino's didn't exist with man why are there so many cave paintings which depict dino's with men?
These paintings being where, exactly??!
