Evidence of the Recent Creation
Living things provide abundant evidence of their relatively recent creation. Claims that life, and death, are billions of years old exploit the fact that we can’t do time travel to see if they are true.

Join us as we examine just a little of the clear evidence that life on Earth is thousands rather than millions of years old.
