see, you do not want to discuss anything, you want to bring assumptions into the discussion.
How do you know how old they are? (by what process) and can you explain why in one animal (a frozen mammoth) the legs appear to be older than the head by the order of thousands of years? How can you explain that.
Also. can you tell me how many fossils would form? Do you even know HOW a fossil forms? it was not because these animals died and thousands of years of sediment landed on them. for by that time, the flesh would have been eaten, decomposed, or (if we look at bones) disintegrated by erosion, wear and tear.
sorry bud, but a fossil can only be formed if an animal dies, and sediment immediately covers its body, before it has time to decompose, be eaten or erode. Which can ONLY be explained by water moving at high speed over the animal dragging sediment over it, and sediment encircling and enclosing it, this sediment Harding in the shape of what is inside it.
If a dead horse is laid out in some field you will not find a fossil of it a million years from now.
ps. I never claimed to be a scientist, however, we can see from your type of responses, you are no more a scientist than I am.
