If “creationism seems possible”, how can you turn around and rule out biblical creation in the same breath? Is there some sort of partisan prejudice driving you to seemingly contradict yourself, or do you have evidence that biblical creation is not true?
I don't "reject Biblical creationism".
The problem comes in when you take Genesis as "literal" and start using Bishop Usher's timetable.
If you don't take Genesis literally, it's actually a pretty good description of the creation of the universe and the evolution of life on earth.
