And to fellow Christians who are young earthers and hang your hat on the speed of light changing a lot. Really? Think about what it means to use your belief in the speed of light being inconsistent to "explain" away the fact that stars and galaxies are billions of light years away. In order to go from a billions of years old universe to one that's thousands of years old, the speed of light would have had to at times been millions of times faster. Think about it. Instead of light traveling 186,000 miles per second you're demanding it had traveled something like 200,000,000,000 miles per second. :)
These physical constants are also important to the formation of matter. Muck around with them too much and atoms (or anything else!) don’t exist! Which begs the question as to how am I typing on this keyboard!
So you put your thoughts to the test please, search and see how many natural clocks there are and see what apparent time each shows long ages or short. Here’s a hint even your own DNA is devolving thru mutations and can’t last more than 20,000 years.
Uniformitarianism is a big fat lie and that is exactly how you defend long ages by assuming you/science knew both the starting conditions and that all things experienced the same boring hum-drum rate of change for eons.
Here’s a website I bet you’ll dare not read nor watch the videos that systematically refutes everything you think you know about history, evolution,and long ages. It answers all the tough questions that today’s science cannot!

Considering your tagline it’s time either defend the Bible or don’t - you can’t have it both ways!
