I must first tell you this. I am not an expert on science or theology by any means. I am an 18-year-old college student. I am a devout Catholic, yes, but my knowledge in science and faith is much more limited than, say, a theologist or a Catholic scientist.
Your worries about your faith in God are understandable. I highly doubt that you are in the minority of Catholics. Other than maybe someone like the Pope, probably every Catholic has had their doubts (I can not verify this, but, as I have had doubts myself, I can at least speak for myself).
I do have some theories on evolution, the universe, and the faith, however, and I think they are reasonable. Allow me to explain.
As Christians, we believe that God is a) Eternally existing, with no end and no beginning. b) Is all-loving of all people, be it a completely innocent child or the most hardened criminal
c) Is all-knowing, yet allows us free will, and d) Is all-powerful in all ways.
Let’s look at “d” now. We know that God is all powerful. Contrary to the logical conundrum, I think God can make a rock so heavy He can’t lift it and still lift it, somehow. His power defies logic yet is a mastery of logic as well.
Now, it is widely accepted in the scientific community that the Universe began approximately 13,730,000,000 (13 billion, 730 million) years old, give or take 120 million years. The observable Universe (that which we can detect) is believed to be about 93,000,000,000 (93 billion) light years in diameter, or about 546,712,590,000,000,000,000,000 miles, or 546 sextillion, 712 quintillion, 590 quadrillion miles. To put this perspective, there are approximately 1 sextillion grains of sand on Earth. And the observable universe is not all of the universe. I have read somewhere that some scientists believe that if the entire universe was the size of the planet Earth, the observable universe would be the size of a quarter. This is an incredible large size and age, and I accept those numbers to be fact. But it all pales in comparison to God. If God wanted, he could make himself bigger than it all, he could make himself infinitely big.
Now, if God, in His majesty, can create this incredibly beautiful, massive, and aged universe, who’s to say he could not have created evolution to form life here on Earth? Isn’t it possible that God could have made Adam and Eve millions of years ago, and the creation story is more symbolic than literal?
God can do more than science allows because God created that which science studies! Science doesn’t rule God, God rules science! The discoveries of these extremely old skeletons only is more proof of God in my mind.
