How do you, or can you prove that god exists?
In what sense?
Are you looking for physical proof or philosophical proof?
I tell you that I have a daughter, and you probably do not doubt me even though you'll never meet her.
If you want to meet God, humble yourself and pray. Read His words, starting with the Gospel of John - it is a love letter.
Welcome to FR!
Hope your time spent here proves enlightening to you.
In which sense do you seek this ‘rock solid proof’? Do you want a Physics answer, a behavioral answer, or an spiritual answer? I ask because fashioning the answer depends upon the framework perspective you now hold to.
