Adam and eve...9 new insights

I've been reading the same version of adam and eve's story, and after mining Quran back and forth for many years i believe it's time to set this straight, here are the insights to consider:

1- adam and eve were first created in the skies, they were living in a heaven on EARTH. After the sin; when allah wanted them out of heaven he used an arabic verb that is used only when u descend from a higher ground to a lower ground, he didnt used the arabic verb for descending from sky.

2- the sin was there responsibility, not adam's alone or eve's alone.

3- there was no snake in the story in Quran.

4- adam and eve werent the first humans, there were humans before tham, when Allah told the angels that he is making a "successor" on earth they wondered, oh allah why would you put someone who will curropt earth and spil blood? That's in Albaqara verse. Now how the angels knew that this creature will hold "blood" in his body? If they didnt already see him before living on earth.

5- the in-breeding is non-sense, adam's sons didnt marry their sisters, they married from the people were living before adam.

6- adam's creation is just alike jesus creation.

7- eve wasnt created from adam's rib, in fact there are clues in Quran that the female were created first.

8- there is no specific date for asam creation, i heard and read many non sense on youtube channels talking that Quran says that adam was created 6,000 years ago, in the whole Quran there is no date set for the creation of any of the prophets. Or even the very told stories in Quran.

9- my personal conclusion is that humanity and till Noah were livig on Atlantic, and the flood dodnt flood all earth, it only flood the land where Noad was living, but that's another story that i'll be talking later about.
