AB,
The human population is bigger than ever, yet in the last few thousand years of recorded history there is little evidence for the many trillions upon trillions of genetic mutations needed to drive human evolution. So has the Creator sat back and said, "Job well done"?
Oh dear. What was explained to you was that there have been trillions upon trillions of
opportunities for genetic mutations, and that for the most part they confer no particular advantage to the resulting organism. Sometimes though they do, and those that do can enable the organism better to thrive in its environment and, when it does, to pass on it's mutated and advantageous genes to its progeny.
You also seriously underestimate the significance of time -
Homo sapiens has only been around for some 150,000 years or so, a tiny amount of time compared wit the three
billion plus years of life on the planet. Adaptations have occurred over that time, but you'd be better advised looking at the common predecessors of all the great apes to understand how evolution actually works.
And no, there's no reason to think the "Creator" did anything because - so far at least - neither you nor anyone else has managed a coherent and cogent argument to demonstrate this creator in the first place.
