Bible was being modified by people,in the coran it's said that the world was not flat before the science prove it.
And why trusting the science when they said someting but after many years this things are wrong.

The Quran also says salt water and fresh water don't mix.

Science is based on observation.  As our ability to observe improves (via technology) our understanding improves and the hypothesis is modified.  Science is never claimed to be a definite, this is absolute fact, but a "this is most likely true based on the data available, and here is how to reproduce my conclusions." "Hey, I can do what he did and get the same result, it is a good answer for now"
