Do you really nag your head over a proof for your existence?
There is a lot of proof for our existence.
None proof of any god’s existence.
If it happens and there is a god(s), which one?
If we exists, does it mean that there must be a designer?
If a designer exists, who designed that designer?
This road is too long to stop, we may get tired before arriving.
There is no proof of the existence of anything else but ourselves. Yet scientists regularly claim to have “proved” something. Not, you know, GOOD scientists, as a good scientist knows that he can’t prove anything, ever, without stepping outside the bounds of science.
As to god(s). By definition, God is not an instance of a genus. He is pure actuality, infinite and complete. IOW, your statement contains a fallacious premise.
If anything exists within time, there must be a cause. Unless time is circular, then there must be an initial cause. If time is circular, however, then science is founded upon fallacious axioms (there is no such thing as cause and effect).
There is no requirement that the designer/designed be a infinite regress, IF THE DESIGNER IS INFINITE. In other words, God can be our designer without requiring a designer.
What you probably meant is: “Which particular model or definition of God is closest to the Truth?” That is a long conversation, but there are some absolute requirements:
- The true religion must be one of both faith and reason. Catholicism is.
- The true religion must not be falsifiable by the general, specific, or natural philosophies. Catholicism is not falsifiable by any system I have yet studied, and no one has been able to do so successfully in over 2000 years.
- The true religion must be based on divine revelation, preferably a revelation that happens multiple times, and can be checked by/with multiple people. Catholicism can be (it is based on a divine revelation given, simultaneously, to a very large group of people, and includes proofs given across time to multiple different people, including miracles up to and including resurrection of the dead.)
- The true religion must have predictive capability. Catholicism does, including thousands of years of prophecies fulfilled, as well as being able to both explain the universe, and predict what will happen, in ways no other system can.
- The one true religion must be timeless. Catholicism is.
and etc. But I won’t list them all.
I am Catholic by an act of faith, AND REASON. And the decision was one of the most carefully reasoned decisions, worked out over the longest period of time, of any I’ve ever made. Catholicism is provably the one true religion, successfully answering every challenge I or other people could throw at it, providing true assertion to every attempt to falsify it.
But, we’re all human, and by God’s gift, we have the right to believe anything we want to, blindly, if necessary. That’s free will.
