First of all, the earliest we can verify that life existed was 3.5 billion years ago, not 1 billion years ago.
Second, I don't put a great deal of significance on the fact that we need a supercomputer to help figure out some biological systems. Actually, for most of the evolutionary analyses that I do as part of my research, an ordinary PC works just fine. But if I were to move into the area of trying to determine exact protein structure, then I might start using supercomputers. The fact that we need supercomputing capacity to figure out exactly how a specific protein folds, however, doesn't lead me to think, "Oh, man, this protein folding is so complicated--God must be folding each and every protein in every single cell of every organism on earth, because proteins are obviously way too complicated to fold by themselves!" Nope, I actually don't believe God is personally folding an unimaginably large number of protein molecules every second. They fold by themselves.
I am glad you are finally recognizing your theories as beliefs and not scientific fact. You are making progress.
