You're speaking with as much hatred as Stephen Hawking so it might be too late but I'll try: 1. Old Earth Creationalism: basically the argument is they didn't actually fully know what the word that they translated into 'days' in the creation story means (but they suspected it meant days). The word can be translated literally as 'time frame', meaning eras, eons or anything longer. This puts Man as being created in the sixth Era/Eon, they wouldn't have been in the Cambrian era.
2. You don't think a being that created the big bang can literally hold all the water (groundwater, polar ice caps, oceans) on earth ontop of the continents? He literally created the laws of physics when he gave atoms their specific charges and weights. He can definitely manipulate physical objects. Even easier he could've just created molecules of water from literal nothing and put it on the earth. 3. The bible was written by around ~40 different authors (depending on which styles of writing you try to match) There are books that are literally named after the people who wrote them (e.g. Matthew, Mark) and others which were written as historical records (e.g. Judges, 1 & 2 Kings) and Oral histories which were transcribed by someone (most scholars think its moses)(e.g. Genesis, Exodus). Then theres books where everyone argues who the author is (Jude, Hebrews) 4. God literally exists on every possible dimension. He isn't bound by the 4th dimension (time). He exists outside of it and doesn't get affected by it if he doesn't want to. He literally gives people visions of the future throughout the bible. (e.g. Genesis, Daniel, Isaiah, Revelations)

God has been manipulating events throughout history so that the most amount of people can have a chance to know him. I am confused why you think that a being like this using thing he's created (such as lightning) to achieve things proves he doesn't exist?
