HELP!! How do i respond to this?

So, i got into an argument with a fellow about God and his existence. And i asked him to give me an logical, rational reason that God exists.
He said "The simple fact that i need to have a reason, that our discussion has a purpose".
So i asked him to elaborate and he basically said: "Our discussion would have no purpose if god wont exist, our discussion purpose its life, this is what we want from this discussion, this is what we want this disscussion to teach us, to have life. If God wont exist (the eternal life), our discussion wont serve a purpose, because everything we would do, we will get to DEAD. But the purpose is life ( life afterlife, eternal life), who gives eternal life? God, therfore God HAS TO EXIST".

His elaborate answer was this: "For truth to exist, there has to exist someting that is not true, like saying: for something blue to exist, there most exist something that is not blue. If not, it wouldnt make any sense to say that something its blue.Why we need to have truth as the purpose, and not the untruth/not true? Not because we see that that thing its doing good to us?Ex: why u say smoking its bad? But now the big problem comes.. what does it trully mean to exist? because the faithfull people say that a true living with God its beyond Dead. For christians, that its heaven, so, good for them its that truth, which help you get to that place. For materialistic people, those who belive that this is all the life we have, the good is that, that help them live a longer life. so which one is right? if you take materialistic people, why is their concept not good about life? Because in their conception, every life its sorted to dead, the only chance of a materialistc guy to live its to pass his genes. so the purpose of our discussion it not the truth, its dead, it has no purpose you could say. But if you take christians, where life its eternal, THEN to obtain that eternal life you must follow the path=> our purpose its the truth - truth exists - truth its necesary - the usefull things are good -good thing give life -our purpose its life - this discussion has a meaning. Who gives eternal life? GOD. 1+1=2 - God is necesairy to exist.

HOW DO I RESPOND TO HIS?? btw sorry for my english

First off he assumes he has the correct answer, but he has no universal unbias answer. All religions work this way.

"Allah is real because the Koran says so."
"Yahweh is real because the Torah and Talmud say so."
"Brahama is real because the Hindu Bhagavad Gita and Vedas say so."
"Buddha is the only path to wisdom because Buddhists say so."

OR, it could be that humans get handed down the religions of their parents from birth for the most part.

By their logic Thor is real because we observe lightening. NONSENSE.

The universe is full of an estimated 2 TRILLION galaxies, each with hundreds of billions of suns each. The universe is 13.8 billion years old. Our planet is 4 billion years old. Our human species in it's current form is ONLY about 2 to 300 thousand years old. 

Does it make sense to you that "all that" time was wasted just to get to us? NO, ok then, nothing to argue with theis person with. He's simply stuck on superstition, a mere desire to have a sky parent.

Even with Hinduism and Buddhism, those are also mere made up social norms parents hand down to their children. Religion is nothing more than a reflection of ourselves, in comic book form.

But the easiest way to watch them stutter and scatter like a cockroach is to say, "Fine, if you think you got it right get it it a lab and have your findings independently peer reviewed."
