this letter (see link and segment below) is why science is awesome. different process to religion. it sits atop a whole heap of facts. its theses change in response to underlying evidence. and that is a distinct process from faith which is unalterable and requires no facts to support it.

"Another problem is that if we can only trust what we have seen with our own two eyes in our short lives, then there’s very little we can know at all. You probably know that there are penguins in Antarctica, and that the Civil War was fought in the 1860s, and that there are fish swimming deep in the ocean, and you also believe that Jesus was crucified two thousand years ago, but if I asked you “Were you there?” about each of those facts, you’d also have to answer “no” to each one. Does that mean they are all false?
Of course not. You know those things because you have other kinds of evidence. There are photographs and movies of penguins and fish, there are documents from the time of the Civil War, as well as the fact that in many places you can still find old bullets and cannon balls buried in the ground from the time of the war, and you have a book, the Bible, that tells stories about Jesus. You have evidence other than that you personally witnessed something.
This is important because we live in a big ol’ beautiful world, far older than your 9 years, and there’s so much to learn about it — far more than you’ll ever be able to see for yourself. There’s a gigantic universe beyond South Carolina, and while you probably won’t ever visit a distant star or go inside a cell, there are instruments we can use to see farther and deeper than your eyes can go, and there are books that describe all kinds of wonders. Don’t close yourself off to them simply because you weren’t there."
