That would take many hundreds of millions of years.

However, the broad scope of evolution is well established and accepted.Consider two methods of estimating the age of some fossils which gave the same approximate result: The agreement of these two figures gives scientists a degree of confidence that the rate of slowing of the earth's rotation is constant, that the rate of radioactive decay is constant, that radiometric techniques to estimate the age of rocks is valid, and that the rugose corals are about 375 million years old.Consider two methods of estimating the age of the moon which also produced near identical results: Again, the agreement of these two measurements gives scientists confidence that the rate of accumulation of space dust has been more or less constant, that the radioisotope method of dating rocks works, and that the moon is about four billion years old.It is impossible to prove that the theory of evolution is absolutely true.The theory maintains that plant evolution, animal evolution and the major geological changes to the earth unfolded over billions of years.The theory of evolution has always been in a state of flux; it is not currently correct, nor is it complete. Each new major fossil discovery has the potential of showing that some part of the theory is wrong.

When this happens, scientists revise their theories slightly to accommodate the new finding.

The discovery of an unmistakable fossil imprint of a human foot inside a dinosaur footprint would form a really good indicator that dinosaurs lived on earth when people were alive.

Quite a few footprints of this type have been claimed to have been found.

This concept of falsification assures that, on the long haul, scientific theories become progressively closer approximations to reality.

Scientists are sometimes able to estimate the age of an object by using two unrelated methods.

A second belief is that, unless otherwise indicated, biblical passages should be interpreted literally.
