It is not perfect by any stretch of imagination.
A lot of people carry genes that cause them problems.
That's some of test of God.
But do you consider that to be a human ?
Here is the problem though: That individual doesn't belong to the same species as us.
So, the best answer to your question regarding the sperm/egg and human is that the one that came first was another species.
I don't know.
they are similaire ,that what mentionned in Quran.2:30
the point is angels don't know the future.
Do you mean it is rare to have a genetic problem ?
Yes
well
You suppose to prove that,how a life could exist from nothing.
All steps, from 1 cell to million variety of creatures .by scientific credible treatements NOT theory.
What are our bodies if not a multitude of cells ?
Our bodies are designed by cells , some said about 37 trillion cells.
like a mosaics in 3D
You can't go from a flashdisk to a robot in one go.
It would take a ton of steps...
Same to human it's would take a ton of steps to make human,is not easy thing.
,who programmed the flashdisk to be robot ,is not the human?
who programmed zygote to build human/creature ?
If you told me evolution or natural selection that's insane , because LOGICALY they had no relation with zygote.
I get some help from
@FearGod about this
how the genetic information is encoded in DNA and how DNA directs the activities of a cell and the development of an organism.

I mean how the information of human/creature body encoded in DNA ?
Have you ever heard about selective breeding before ?
variaty in one kind,don't creat new kind.
