Were you there "millions of years ago" when colorado was covered in water? I didn't think so. My point is you underestimate how much of your knowledge is also taken on by faith, and although I could bash your faith in many things, I will not as this is not my goal and generaly not very productive anyway. I will continue defending my faith untill the day I die, right now I believe the words of C.S. Lewis (who used to be an athiest btw) are quite appropriate reguarding Chritsitainity.
From
Mere Christianity:
"In other words, I believe it on His authority. Do not be scared by the word authority. Believing things
on authority only means believing them because you have been told them by someone you think
trustworthy. Ninety-nine per cent of the things you believe are believed on authority. I believe there is
such a place as New York. I have not seen it myself. I could not prove by abstract reasoning that there
must be such a place. I believe it because reliable people have told me so. The ordinary man believes
in the Solar System, atoms, evolution, and the circulation of the blood on authority—because the
scientists say so.
Every historical statement in the world is believed on authority. None of us has seen the Norman
Conquest or the defeat of the Armada. None of us could prove them by pure logic as you prove a
thing in mathematics. We believe them simply because people who did see them have left writings
that tell us about them: in fact, on authority. A man who jibbed at authority in other things as some
people do in religion would have to be content to know nothing all his life."
And also: "There is no use saying you choose to lie down when it has
become impossible to stand up. That will not be the time for choosing: it will be the time when we
discover which side we really have chosen, whether we realised it before or not. Now, today, this
moment, is our chance to choose the right side. God is holding back to give us that chance. It will not
last for ever. We must take it or leave it."
These are from Chaptrer 5 of book 2..
I highly suggest you read Mere Christianity, The first half is even written from a secular standpoint. Here is a PDF.
