Jesus explicitly says
he'll return within his disciples' lifetime, so this hand-wavy excuse doesn't wash.
Ignoring Jesus, there's the whole Genesis farce. We can demonstrate that the universe took way, way longer than seven literal days to form into its present state. "Alright, it's a metaphor, Biblical 'days' are much longer than 24 hours!" In which case, I wonder how exactly much longer, because God fucked up and created plants before there was any Sun to nourish them. D'oh!
Actually...as written I think it was light that was created before plants. Where do you think that light came from? There are scientists who have postulated that light can come from black holes believe it or not.
"The radiation being described here is not coming out of any kind of matter-the usual source of light energy. The region around the black hole is quite empty of matter Instead, this radiation is coming out of empty space itself! (P. C. Davies, Uncensoring the Universe,
The Sciences, March/April 1977, p. 7)."
And what if a billion years is a day somewhere in a universe of creators?
Anyway there is no point in debating this.
The only thing that actually is relevant is:
Article 9: Freedom of thought, conscience and religion
