@FBM,
How to prove the existence of God on critical thinking?
First before anything else, we must concur on the concept of God; do you know that, because unless we, you and I, have the same concept of God, then it is useless as we are not talking about the same thing.
Here is my concept of God, the creator and operator of the universe and of everything with a beginning.
When you know that concept, then we can proceed to prove i.e. to look for God in the universe; can you understand that?
What I notice with atheists is that they are always dodging serious critical thinking, insisting like that the party making a claim must prove his claim -- it is not really that simple: party making a claim must prove it.
Have you ever read something like the party in possession is more weighty than the party without any possession, that means the party with an opinion is more intellectual than the party without any opinion except denials.
That is correct generally, party making a claim etc., but the party that is into the exchange in the anti camp must know what it is to prove from critical thinking; otherwise even if the party making the claim has proven the claim, the opponent party will not know that the claim is already proven, because he does not know what is in concept the thing to be proven: what he has are cliches and insults against the object to be proven, and also engaging himself in flippancies, instead of taking to critical thinking.
So, first, do you have a concept of God, if you do, then we can work on your concept and my concept, to come to a mutually agreed on concept of God; from that point onward I will show you that God exists, and you will see it if you are intellectually honest and conversant with critical thinking, grounded on truths, facts, and logic.
You will realize at this point that you are now looking for ways and means to make up more cliches and flippant utterances, instead of taking up genuine thinking, on truths, facts, and logic, to delve on the question, Does God exist?
Next escape route for atheists, they will proclaim that it is impossible to prove a negative, so you don't have to do anything at all, but to make negative statements and say no need to prove them because it is impossible to prove a negative.
About that more, if and when you bring up that escape route.
Now, another cliche or slogan of atheist masters: certainly you were not born a theist, although you were born without any knowledge arrived at from contacts with truths, facts, and the use of logic, that is not the same as being born an atheist -- except that your atheist masters have succeeded to condition you to not ever think on truths, facts, and logic, but to swallow slogans which mean nothing but are fallacious words, catering to your emotion of self-arrogance, like very baby is born an atheist.
Okay, are you willing to postulate, at least get acquainted though not accept it, that the concept of God that does God justice is that God is the creator and operator of the universe and of everything with a beginning.
Study that concept and tell me what objections you have against the concept as concept; mind you, I am not asking you to accept the concept as already representing the reality of God, but just as a concept, like a treasure map is a mental guide to know how to get to the site of a treasure if indeed there is a treasure in the site indicated in the treasure map, so also the concept of God, it is a map which if you can read the concept as like a map, by which you and I can go forth and arrive at the existence of God.
Okay, examine my concept of God, the creator and operator of the universe and of everything with a beginning, what objections do you have against such a concept of God.
When you are going to transmit your post, see whether you really have replied to the question immediately preceding these last words from me.
