My computer is a very complex gadget and it was designed by many designers, so why must the universe have only a single designer and not many designers?

What I can't understand is why you invoke improbability and yet you will not admit that you're shooting yourself in the foot by postulating something just as improbable, magicking into existence the word God.

It is a simple logic truth that, short of mass emigration into space, with rockets taking off at the rate of several million per second, uncontrolled birth-rates are bound to lead to horribly increased death –rates. It is hard to believe that this simple truth is not understood by those leaders who forbid their followers to use effective contraceptive methods. They express a preference for ‘natural’ methods of population limitation, and a natural method is exactly what they are going to get. It is called starvation.

Very close cousins like humans and chimps have almost all their genes in common. Slightly less close cousins like humans and monkeys still have recognizably the same genes. You could carry on right on down to humans and bacteria, and you will find continuous compelling evidence for the hierarchical tree of cousinship.

Granted, we may try to help our own family members because they share our DNA. Or help someone else in expectation that they will help us later. But when you look at what we admire as the most generous manifestations of altruism, they are not based on kin selection or reciprocity. An extreme example might be Oskar Schindler risking his life to save more than a thousand Jews from the gas chambers. That's the opposite of saving his genes.

Even if it were true that evolution, or the teaching of evolution, encouraged immorality that would not imply that the theory of evolution was false.

It is an essential part of the scientific enterprise to admit ignorance, even to exult in ignorance as a challenge to future conquests.
