[75.38] Then he was a clot of blood, so He created (him) then made (him) perfect.
Science proves that we were never a clot of blood when we developed.
[23.14] Then We made the seed a clot, then We made the clot a lump of flesh, then We made (in) the lump of flesh bones, then We clothed the bones with flesh, then We caused it to grow into another creation, so blessed be Allah, the best of the creators.
Actually, the bones were never "clothed" with flesh, since the bones formed from within the flesh.
And that clot was already a lump of flesh.
