God creates. People pro-create. God created life. We simply pass it on.
Your question is similar to a child asking its parents, why did you give birth to me knowing I would suffer and die?
The answer is of course that despite the suffering you might experience the beauty joy and wonder of life.
God's gift of life does not have to end. People choose their end by rejecting the Giver of life.
And really, expecting God to give more life to those who refuse to acknowledge Him as the
giver in the first place? Yeah. Hopefully we can all see how ridiculously unrealistic that is.
