Is it not easy to see that if christians are right and God exists...?

If anything supernatural affects the natural in a way that makes that natural thing not follow natural laws, then whatever was affected becomes supernatural itself by definition. Therefore, either the supernatural does not exist, the supernatural cannot affect the natural (making it effectively nonexistent), or the natural does not exist because the supernatural could make it break the natural laws.

I prefer to think there are some things in the universe that are natural (i.e. "real")

Your question would greatly upset a blind person. They can't see why kids like Applejacks so much either.

The don't though. It tastes like sawdust.

But let's follow your line of thought,

let's give a hypothetical:

I have written a bible called the Necronomicon and it's all about various Gods which thousands of people worship. Now, someone says that they're not true. A horrifying eldritch being with a squid for a face just simply cannot exist. The retort is that these beings are so far beyond human comprehension that there is no way to fully grasp them, and therefor can not be disproven.

The sun is secretly fueled by the souls of dead anti-semites. Can you prove that the sun is eating souls? No. Can you prove that it is eating souls? No.

Although I would question why God would write a bible directed at humans only to have it go so far above our heads or why he wouldn't make us able to understand him to begin with.

That's a good point! Yes, truly it is obvious to those who know the Lord, and by instinct it should be obvious to all people. God has shown us his works through creation. What more proof do we need than that to start believing? We are without excuse for not believing in truth. God gave us his word.

Romans 1:18-20 (NKJV)

18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness, 19 because what may be known of God is manifest in them, for God has shown it to them. 20 For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse,

The evidence is right in front of you. The problem is all that you have grown up being given to you from the world. The absolute truth of reality does not lie and the Bible agrees with absolute reality.

Notice that all laws work together which shows only one Supreme Being. Logic and reason always bring you to God, not away.

Do you think such a being can be defined in a book 1 1/2 inches thick? If such a being existed he would not be biblical.

The Bible could easily be made-up by someone, or a collection of hearsay that went through years and years of telephone before being recorded.

Also, the Bible speaks of God interacting with people and breaking the laws of psychics, IE a bush on fire that isn't eaten by the flames. If God wanted to prove himself, he would interact like he once did.

Just my opinion on it.

Science at least attempts to explicate the things that we experience in the natural world. I can appreciate that inordinately. But there are some things that occur that science can't even touch nor hope to explain in terms that would make sense to us.

For the joker who keep reiterating and has been talking about Zeus and other gods, Ask those gods to prove themselves in your life if you believe so strongly in their existence...

As for me, the God of the Bible challenges us to TEST HIM for his Validity and realness...I did so many many years ago on more than several handfuls of occasions and each and every time the God of the Bible has proved himself to be gifted in the abundance he allowed me on earth Abundance in peace, happiness, fullness of success and in finance..Something that the Zeus gods have not yet come forward to prove themselves with.

The way I like to see it.

Christianity=brainwashing and door to door bullshit

Is it not obvious that Zeus and the other Greek gods exist?

Hades will punish you for blasphemy if you do not stop spreading this nonsense.
