Some people believe God created the Earth 6,000 years ago and Adam and Eve along with it. They don’t accept the rather compelling, irrefutable evidence proving the Earth is about 4.543 billion years old. My father saw it. It bothered him so much he rejected religion and called himself an agnostic, which he defined as someone who wanted to believe but couldn’t. He believed in science.
But there are some problems scientifically figuring how aquatics crawled out of the water or how amino acids chemically evolved to produce DNA. All the pieces have not fallen in place. There are also some archeological anomalies here and there that seem to conflict with accepted time frames.
Nonetheless, evolution happened. Or so it appears rationally.
My dog offers pretty good evidence. Dogs evolved from wolves with human help. Even today people create different breeds of dog. Look how many varieties of dog breeds exist today. All descended from wolves due to human intervention and selective breeding. It’s what happens naturally over millions of years in the wild but accelerated in dogs because humans made the decisions rather than natural survival of the fittest.
