A simple thought experiment for those who believe the Earth is of the order of 5,000 years old and who do not believe in evolution:
If the story of Adam and Eve is
literally true, then when only Adam and Eve existed there could have been a
maximum of
4 different human eye colours.
This would be the case if the 4 human eyes (Adam had two, Eve had two) were all different colours.
However, there are now more than
25 human eye colours.
Many people who do not believe in evolution hold this position because they reason that a living thing could not possibly have some feature that its ancestors did not have - e.g. how could a sea creature evolve into a bird over millions of years...
If you take this position, how do you explain the development of human eye colours, as described above?
