The human being is the most complex creature on the planet. Every person has a distinctive identity. This identity is characterized by a unique fingerprint, distinctive eye print and exclusive DNA which carries most of the genetic instructions used in the development, functioning and reproduction of the human being. If uncoiled, the DNA in all the cells in your body would stretch 10 billion miles, from here to Pluto and back.

Verily We created man from clay then We placed him as a drop (of sperm) in a safe lodging; Then We made the sperm into a clot of congealed (solid) blood, then of that clot We made a fetus lump, then We made out of that lump bones then covered the bones with flesh, and then produced it another creation.
Quran, 23:12-14

That is the Knower of the unseen and the witnessed, the Exalted in Might, the Merciful. The one who perfected everything He created and began the creation of man from clay.

Then He made his posterity out of the extract of a liquid disdained. Then He proportioned him and breathed into him from His soul. And He made for you hearing and vision and hearts; little are you grateful.
Quran, 32:6-9
