Why do theist insist that Atheist prove a god DOESN'T exist? If you don't see, hear, taste or feel something... that's proof. Is it not?

A last desperate attempt to bolster their dwindling faith.

They're like children in a playground, if you ask them for proof their only reply is "no, you prove it".

You claim that God does not exist because there is no evidence of His existence

this must mean you have proof He does not exists because you would hold no belief that God does not exists, without evidence....would you

So we keep looking for you to provide this illusive truth

Did Pluto exist before we could see it?

They're REALLY bad at logic and they KNOW they cannot prove their God exists so they try to shift the burden of proof. It's the only recourse they have. They'll jump through all kinds of hoops to try to say it's not a burden of proof fallacy too even though it 100% is. Consider if they used that same "logic" anywhere else in normal society:

"I don't own a Ferrari"
"Oh yeah, PROVE IT!"
"Uh... what?"

"Vampires don't exist"
"Oh yeah, PROVE IT!"
"Uh... what?"

"I am not telepathically communicating with aliens in the Orion Nebula"
"Oh yeah, PROVE IT!"
"Uh... what?"

XD

But the word a-theism means it lies on you.

No, that is not proof.
But yes, the burden of proof lies with the person making the claim.

You are correct but because theists have no evidence for heir claims they try to shift the onus on proof onto atheists.

They do not know how to tell fiction and reality apart.

If they knew, they probably would not be theists.

No need to prove anything. God has shown sufficient to all.

Those that deny simply don't want God.

Sadly, theology either don't understand that concept, or they hide behind logical fallacies to validate their believe to them just as much as they try to do to others

In logic
and in formal debate
and in almost all other situations
there is no burden of proof on either party.

It is just as "wrong" (unreasonable) for a Christian to demand:
- Atheists, prove that God does not exist!
as it is for an atheist to demand:
- Christians, prove that God exists!

Both are cases of a person
who lacks both authority and sound reason
attempting to unilaterally assign a burden of proof on the opposing party.

Typically this is used as a "dodge", an attempt to trick the opposing party into "doing all the work" while the erstwhile assigner of burdens of proof sits back and watches his opponent struggle to lift the imagined burden.

Why do theist insist that Atheist prove a god DOESN'T exist?

- We told them to prove their fantasy exists so with their third grade mentality, they think saying - prove god does not exist - is actually intelligent.

The burden of proof is on both sides of the argument.

You cannot see,Taste, hear, or feel a Spirit? But that doesn't mean it is not there.. !!

No, if you cannot comprehend something, that does not mean that it does not exist...we cannot really see neutrinos, yet we know that they exist.

No, many people see things that are not there and hear voices too. They feel they are persecuted when all they are is paranoid.
Never trust your senses. Drugs, alcohol and chemical imbalances in the brain can alter them.

My cryptic expressions of my superiority complex proves my deity exists. But wait, every group seems to do that...

Umm, I have toast patterns of my deity, so checkmate, atheists and other religions!

yes youre right. good point! :)

but,... they claim the can feel it

I have seen the Holy Spirit. God is personal. If your mind wasn't blind maybe you could see it like billions of people have.
