“life” writ large is the “gift of G-d”
that’s what all creation is
but G-d allowed/allows humans and our free will to use what G-d’s creation gives us, which includes our reproductive capabilities - yes, our free will (or, maybe you’re a Muslim and believe (as Muslims do) that we do not have, that G-d did not give us, free will)
that does not make every individual instance of life that humans create a “gift of G-d”, because G-d is not micromanaging all our individual moment-to-moment decisions, “life bearing” and otherwise
You believe that there are people walking around whose very lives are not a gift from the Creator?
Cripplecreek’s niece is not a gift from the Lord? She’s just an accident created by a rapist that G-d will muster up the goodwill to love anyway?
I don’t understand what you’re saying. All a man can do is put his sperm in a position to fertilize an egg; whether it does or doesn’t is beyond his control. Man does not create life. Only G-d can create life. It’s not an automatic thing that has to happen if all the variables are just right - like a building falling down if a plane flies into it, or gasoline exploding in the presence of fire. All the variables can be right, and sometimes conception will occur and sometimes not.
