well I agree that TOE is tentative. it is very uncertain, and a faith call and since you agree that FAITH has no place in SCIENCE, how can you take that leap (of faith) for TOE?
Where is faith required? I fail to see where faith is required when there is evidence to support every part of the ToE. Without time travel we will never be able to "prove" that evolution occured in the past through random mutation and natural selection. However, all of the existing evidence points towards all organisms sharing a single common ancestor and that changes over time were due to random mutation and natural selection. No faith is needed since the theory is supported by evidence and consistent with all of the evidence.
Christianity, on the other hand, does require faith since there is no scientific evidence for the Resurrection nor for the existence of God. There is also no evidence for a 6,000 year old earth, the special creation of organisms, nor a world wide flood. In fact, all of the evidence contradicts such beliefs.
I really don't understand why you claim that the ToE requires faith. Science is not about "believing" something, it is about accepting a theory as being consistent with the evidence we have at hand. Nothing more, nothing less. You can still believe that the theory is wrong, but you must do so with the understanding that it is consistent with the evidence, the evidence we find in God's Creation.
