Grt. I wanted to hear the same statement about Evolution and Survival. So your statement about God cruelty is meaningless as well. We dont plant a plant after eating one or we dont try to bring one animal after eating one...but GOD has a made a process which takes less and gives you more at least trice. Like as per statistical data each second one human being leave this world and three comes and it is more nowadays. If no one dies just imagine the process...may be u will get a proper evidence for Evolution which you guys dont have still except some fossils.
