You made some good points there. I always found the moral argument to be viable but 1 of the weakest ones available.
I prefer:
the cosmological argument
1. The universe had a beginning
2. Anything that had a beginning must have been caused by something else
3. Therefore, the universe was caused by something else
cosmological natural theology
1. Time, space and matter came into existence at a certain point in the finite past.
2. Since time, space and matter began to exist they had a cause.
3. Therefore, whatever caused them was time-less, space-less and matter-less.
the teleological argument
1. All designs imply a designer
2. There is great design in the universe
3. Therefore, there must be a Great Designer of the universe
the ontological argument
1. God is defined as a being than which no greater can be conceived.
2. Such a being can be conceived.
3. If there were no such being in reality, then a greater beingnamely, a being than which no greater can be conceived, and which existscan be conceived.
4. Yet nothing can be greater than a being than which no greater can be conceived.
5. Therefore a being than which no greater can be conceivedi.e., Godmust exist.
Dostoevskys argument from the consequences of positive Atheism
1. If atheism is true then man is the chief of the earth
2. If man is the chief of the earth then he can abandon absolute standards
3. If man can abandon the absolute standards then everything is permissible
4. Therefore, if atheism is true, everything is permissible
The argument from joy
1. Every natural innate desire has a real object that can fulfill it
2. Human beings have a natural, innate desire for immortality
3. Therefore, there must be an immortal life after death
