1) If God can't be seen, it's because he's invisible
2) If God can't be touched, it's because he's incorporeal
3) If God can't be heard, it's because he communicates telepathically
4) If God can't be tasted, it's because you lack the "taste God gene"
5) If God can't be smelled, it's because he used antiperspirant
6) If God can't be detected in any way, it's because we lack the means to detect him
7) If God doesn't talk to you, it's because you're not listening
8) If God doesn't make sense, it's because you don't understand
The list of excuses goes on and on and on. No matter what proof one tries to offer to disprove God, there is always a possible explanation---no matter how far-fetched---to "disprove" your proof that God doesn't exist.
