I have. Trust me I have. Long ago when I was sould searching and deciding whether to really follow the faith of my fathers, or trust in human knowledge.
The bottom line; it always boils down to logic and moral law.
I wholeheartedly believe in adaptation. But a fish, will always be a fish, and a duck a duck.
All honest Christians I have ever known have questioned our faith, and came out with a solid foundation.
I think the creation and flood descriptions in Genesis are allegorical and certainly teach lessons but aren’t literally true. There are other portions of the Bible that are clearly allegory. It doesn’t mean they are “not true” just because they teach a lesson rather than detail an occurance. There is also a very fuzzy line between the Old and New Covenants. Should we or shouldn’t we eat shellfish. An apparent contradiction doesn’t hang me up and some things are clearly miracles like the virgin birth and resurrection and, as such, aren’t subject to scientific inquiry. Unlike the flood, for instance, science cand verify the events leading up to them and can record changes as a result of the miracle.
That’s just my approach as supported by other believers far brighter than I.
