Uh ... no ... it isn't.
You have your beliefs and I don't mean to denigrate them ... so this should be taken as an explanation as to why I don't believe it ... not why you shouldn't.
You can't prove anything in genesis. You can't demonstrate Adam and Eve and the snake and the Apple. The best anybody can do and say "there's no other explanation, so it has to be God" ... no, it doesn't. There have been thousands and thousands of things that man didn't understand that were attributed to God or "Gods" that have later been explained.
You can't demonstrate that a 300 year old man built an ark and gathered all the animals in the world. You can't demonstrate that God shipwrecked Jonah and then allowed him to live 3 days inside a fish (is it a fish or a whale, because a whale isn't a fish ... so apparently Christians don't know the difference between fish and mammals, but I'm supposed to believe they know how everything got here) and then had the fish spit him out where he wanted him to be.
Then you have supposedly two different events in which Jesus fed thousands by multiplying loaves of bread and fish ... two events that are eerily similar but slightly different ... so it really seems like a different retelling of the same event ... and if the details differ in the telling of the same event, then how does anybody know what really happened?
God loves us all ... but if you don't swear your undying devotion to him then he'll cast you to hell for eternity? Uh, no. Supposedly murderers and rapists can "find" God in their last months and be forgiven ... but a person that lives a kind and generous life without "finding" God goes to hell? Uh, no.
To have this conversation you would have to understand "historicity." Historicity means a historical document has names, geography, culture, etc., consistent with the time period about which it purports to report. Where those items are know independent of the Bible the Bible proves consistent with those items. So the story of Jonah is not found independent of the Bible but the names, geography and culture are consistent with what can be independently verified.
Speaking of Jonah, to speak of Jonah not knowing the difference between fish and sea mammal is to speak anachronistically. It would be 2,000 years later before anyone would not consider a whale a type of fish. Besides...
"Wherefore he had no fancy for lowering for whales after sun-down; nor for persisting in fighting a fish that too much persisted in fighting him. For, thought Starbuck, I am here in this critical ocean to kill whales for my living, and not to be killed by them for theirs; and that hundreds of men had been so killed Starbuck well knew."--Chapter 26, Moby Dick.
What an ignorant sort that Herman Melville was.
The two stories of Jesus feeding multitudes are similar but not the same and are included for different purposes. Jesus, after performing many miracles in demonstration of God's power in him, teaches the people of Israel on a mountainside in Galilee, west of the Sea of Galilee. After teaching them Jesus take two fish and five loaves and feeds the 5,000 from the twelve tribes of Israel. The leftovers fill up twelve baskets full. Then Jesus goes to the east side of Galilee where the seven nations of the Canaanites settled, but only one person, a demoniac, is there to greet Jesus. There he heals the demoniac. The demons in the man leave and go into pigs which rush down the mountainside and drown in the sea. The now former demoniac comes to full health, but the Canaanites see this and ask Jesus to leave region because they are frightened. The former demoniac asks Jesus if he can come with Jesus. Jesus tells him to stay and tell others what he did for him. Jesus leave and then returns. This time 4,000 from the seven nations of the Canaanites are there waiting on him. The demoniac was the key to reaching the region. Jesus teaches them and then feeds them. This time the leftovers fill seven baskets full. In the Old Testament God is call El Shaddai--the God who is more than enough. Jesus feeds the twelve tribes of Israel and there are twelve baskets full leftover. Jesus demonstrated he is El Shaddai, the God who is more than enough for the Jews. Jesus feeds the seven Canaanite nations and there are seven baskets full leftover. Jesus demonstrated he is El Shaddai and more than enough for the Gentiles. The lesson is clear--God is more than enough for your every need no matter who you are.
As to your conclusions on heaven and hell and what God is looking for, read Mark 12:28-34, then get back to me.
