That life originated in an aquatic environment is evident in that life is far, far more deeply diverse in the seas than on land and how essentiql water is to all physiology. No special divine knowledge needed. And even there, the idea of an primordial ocean is far more widespread than the Bible.
Also, it’s quite a jump from
And God said, Let the WATERS bring forth abundantly the moving creature that hath life, and fowl [that] may fly above the earth in the open firmament of heaven.

It is interesting to contemplate an entangled bank, clothed with many plants of many kinds, with birds singing on the bushes, with various insects flitting about, and with worms crawling through the damp earth, and to reflect that these elaborately constructed forms, so different from each other, and dependent on each other in so complex a manner, have all been produced by laws acting around us. These laws, taken in the largest sense, being Growth with Reproduction; Inheritance which is almost implied by reproduction; Variability from the indirect and direct action of the external conditions of life, and from use and disuse; a Ratio of Increase so high as to lead to a Struggle for Life, and as a consequence to Natural Selection, entailing Divergence of Character and the Extinction of less-improved forms. Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.
And finally, yes, Darwin was one of the greatest scientists ever, no, he did not recant on his death bed, and no, Darwin’s theory stands on its own merits and has been improved and revised considerably from there so your ad-hominem arguments are completely irrelevant.
