There is no evidence for the existence of God(s), nor any evidence for the continuation of consciousness beyond death. There is a large body of testable evidence of organisms that are unsafe for human consumption. We cannot prove whether or not any changes introduced by humans via genetic engineering, whether intended or not (such as random mutations) will result in an unsafe product. The worst case being that we create a strain of organism that is superior to those we currently have, displacing all others in the environment and being unsafe for human or animal consumption, and if it is a staple crop one that leads to more starvation not less. As far as feeding an increasing population, the simple answer is not to have the increase. Even then our current agriculture system is heavily based on fossil fuels. Increasing cost of production and distribution if not outright decline in fossil fuel output is much more likely to lead to starvation.
