Christians, if GOD is real, then why do you tell people that GOD is real? Shouldnt it be known to everyone that GOD is real? ?

How could everyone know

if no one told them?

For example:

if no one ever told you about the planet Neptune

would you know that Neptune is real?

Of COURSE someone had to tell you.

No, people exercise their freedom to ignore God, even to fantasize that he doesn't exist.  Sometimes people need a gentle reminder.

If atheism were true, then why do you need to tell people that there is no God?  Shouldn't it be known to everyone that there were no God?

The gospel should be known, then on that same basis.  But there is the :Great Commission, of Mt. 28:19-20.

You make a valid point.

It's not that it "should" be known, but rather it is known, but just lied about.

Until recently I was unaware of the Brown Trucking Company's use of lie detectors in interviews which proved that all atheist lie when they say they don't believe in God.

Knowledgeable Christians have known better than to waste time proving God exists, just like they don't waste time proving to a sun-denier that the sun exists.  Anyway, we know that all atheists are lying about their belief in God, either that they do believe he exists or or not sure.

God already told us. No one can come to him unless they are drawn by the Father. So there really isn't anything on this Earth that isn't supposed to be here. God doesn't want everybody.

John 6

Jesus answered. 44 “No one can come to me unless the Father who sent me draws them, and I will raise them up at the last day. 45 It is written in the Prophets: ‘They will all be taught by God.’ Everyone who has heard the Father and learned from him comes to me."

I have never told people God is real.  I have told people He is our heavenly Father and our Creator because many are ignorant and don't know these things.

IT COULD BE KNOWN IF PEOPLE PRAY...BILLIONS ARE BORN AGAIN!! U COULD BE NEXT...THE UNIVERSE did not make itself.

It is known to them......Every culture in history has recognized some type of deity according basic Anthropology 101.

Romans 1:19-20

For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. 

If Australia is real, then why do you tell people that Australia is real?  Shouldn't be know to everyone that Australia is real?  

And yet its existence was know to the majority of the world until the 1600's and not colonized by anyone until the late 1700's.  People have only known about it for about 300 years even though it has existed for thousands of years.

Calculus existed before Newton discovered it in the 1700's.  Yet people did not know about it. And even after Newton discovered it, people still have to be told about it and have it explained to them.  

Just because something is real does not mean that everyone instantly knows about.  So that is not a logical argument against the existence of God.

BUT... in the reverse, it is interesting that we have yet to find a culture anywhere in the world were the concept of god(s) does not exist.  Even where there is no one to tell people about the idea of "god", they develop that concept.  Granted, their understanding of it varies widely.  But then their understanding of number and counting varied widely across societies.  Some developed "zero" and others did not.  Some developed "places" and others did not.  Some developed algebra and others did not.  But the only came up with some concept of "numbers".  And so every society has come up with some concept of "god."

So the idea that people have to be taught about god is false.  The idea that people teach each other about their understanding of the concept of god is true.  

Do you know words without ever being taught them? Math?  How to read? All of these things are learned. Education itself is nothing but pure indoctrination. That's all it is. A big dose of "Here's what we know  so far and here's how we apply that knowledge."
