You're kidding, right? Have you ever heard of Down Syndrome? Just one of the many mutuations that goes wrong, quite frequently, actually, and millions of people immense suffering every year.
Harmful mutations happen all the time in nature.
But, interestingly enough, they always seem to be the SAME mutations, or mutations that result in the same effects. Random mutations causing random variation does not seem to occur.
And do Down PARENTS pass that BAD mutation to THEIR children?
Yes I have. We're talking about the time of Creation, not the current environmental situation. Who knows what causes this? But one thing for sure, they are little angels, and their parents are the nicest people you will ever meet. God gives us all different challenges to bring us to a greater faith.
Also, again, there are no dinosaurs with faulty mutations that have ever been found. We're speaking of how we got here. Not to mention the fact that the 'big implosion' or whatever theory they call it when the galaxy retracts like a big rubberband snapping back into place: On NOVA, measurements show the galaxy is not only NOT slowing down, and NOT snapping back, but it is EXCELLERATING outward, defying decades of scientific thought.
I wish I could have heard the sound of God's laughter when they calculated that one.
