Evolutionists and Athiests imagine Evolution worked by:
1-Species changing by mutations, genetic drifts, ....whatever
2-Resulting species that fit its environment survived
3-Other who did not, distinct or did not survive for many generation
For this process to be true, millions (even billions) of variations would have existed over time
and as "Does not fit" is not always fatal, they should have survived for some time and generations as well (million or thousands of years)
Not only that, as the process is not controlled by any intelligence, a lot of (illogical) variations must existed
Where are the fossil records for such mutated "Unfit" species?
They imagine that the existence of mutation, proves that every thing came through it!
They think that distinction of animals proves evolution, but it is actually disproving it!
