We all know that God has created the Prophet Adam, and presumably he created Eve in the same way.
Medical science rejects such an assumption.
That would be very helpful for all of us. The first thing that I would like to say about this question is that when something relates to God's power or how He does whatever He wishes to do, or how He creates, then we should accept what is stated in the Qur'an or in an authentic Hadith without any reservation. We know that God has power over all things, and he is able to accomplish His purpose easily, and without difficulty. We know, for example, that man was created from clay and then God breathed of His soul into him. God certainly could have created man from some other substance, or without using any substance whatsoever.
