I recall studies which focused on the explicit Hebrew in Scripture, where the flood was caused by fountains from the deep. There is also conjecture of a water barrier over the atmosphere, which was pierced and then collapsed.
Just has the flood may have came from waters not on the surface, the sea floor may have spots where the waters receded back into the deep and the oceans now are closer to where they were upon the Deluge.
Gen 6 and history of Giants, Nephilim, and evil spirits also plays into the study.
If one doesn’t ignore the evidence, there is substantial evidence consistent with Scripture.

Gen 7:11 In the six hundredth year of Noah’s life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened.
