This thread is an example of what happens when we start out with an unproven premise and then build on it in a way that fits in with our personal beliefs.
The species that presently inhabit this tiny dot in the universe, that we call earth, are only a small percentage of the species that have lived. Most species are extinct and all creatures eventually die. That's the way it is. Homo sapiens are a very recent species. Suffering has always been a part of life on this planet for all living creatures.
Living on earth involves fighting for survival and competing for limited resources. Plants and animals all do this and there are survivors and losers. It only takes a drought for thousands of animal to die of thirst. Many animals live to eat others or be eaten. Humans have also been busy killing each other for their entire existence. Humans are also at the mercy of nature, though modern science has helped to reduce pain and suffering in many ways.
No one is to blame for the suffering that takes place or praise for the pleasure we experience. We are all part of a living planet which is constantly changing. Life simply is. We are a part of what is. How long the human race will survive depends on how well we adjust to the challenges that we face and control the rate of childbirth. But as a race we have to stop blaming a boogeyman in the sky and Chanel our resources into developing practical solutions.
If believing in a god or gods bring comfort, then the belief serves a useful purpose. But if that belief interferes with our ability to make rational choices, becomes an excuse to harm others, or prevents us from taking responsibility for our individal actions, then it becomes a hindrance to limiting suffering rather than a help.
