Oh I can't believe I'm rising to this... but needs must
'It predicted a spherical earth while many people were flat earthers.'
No it doesn't. Young Earthers like pointing to a phrase in Isaiah which uses the word 'circle'. They don't so often mention the mentions of God laying out the Earth with a compass in Job and Proverbs. You can't make a sphere with a compass.
And there were never many flat earthers. The concept of the Earth as a sphere long predates the Bible, it caused few problems for the Ancients or the medieval world. It's 21st Century Kansas that seems to have trouble with the idea of the Earth just being a lump of slowly cooling iron, nickel and silicon hanging around a gloomy part of the Milky Way that's been going gently downhill since the early Caenozoic.
'Genesis states God created light before the sun and stars which is consistent with the Big Bang Theory.'
Well if you mean that there was light before the stars then yes, the Bible is consistent with the Big Bang theory (but then gets understandably side-tracked by the whole begetting bit when it could have been explaining the role of deuterium in the early Universe).
However, your theory falls apart when you actually - ummmm - read the Bible. Doesn't the whole 'Now the earth was [a] formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.' rather suggest that even if the light appeared without stars, it's irrelevant because the water got there first?
And if you do want to discuss creation in Genesis - which one do you want? There are two irreconcilable tellings of the act of creation in Genesis 1 and 2. Either God is even more unknowable than we thought, or there was some sloppy proof-reading going on in early Palestine.
Genesis is myth and epic poetry. It's about as useful at explaining the Universe as a copy of Lord of the Rings with the saving grace that it's out of copyright and there are no crappy songs.
'It describes cities that don't exist (for which it has been criticised), but archaeologists continue to dig them up.'
You're really going to need to explain that, preferably with the aid of diagrams - they don't exist but they get dug up? I'd like to see that on Time Team. If you mean cities that have been lost then that's a different matter; but no one is seriously saying there are no historical events in the Bible - it's just that they've been buried under layer upon layer of badly translated myth.
If Bible says there was a city in a location in a (fairly tiny) part of the world with relatively little habitable space which has been settled for tens of thousands of years - and we dig up human remains - that's hardly astonishing.
If on the other hand we were to find the Ark of the Covenant, some fossilised manna or an eye witness account of the end of Sodom (preferably in the hand of the author who had been pinned down under an easily carbon dateable catamite by a large lump of falling brimstone) - that'd be different.
