Egyptian gods? Fairy tale

There's been something bothering me for a long time. Do you remeber, when you were teached about first primitive human cultures? Do you remember what was written in almost every history book? About gods of those primitive cultures?

First people didn't know a lot. And whatever they didn't know, whatever they couldn't explain, they just told it was a god. We had then god for lightning, for raining, for floods, for good harvest, for bad harvest etc. And you were teached this like this is absolute foolproof truth. Then you could move to less primitive, but still enough primitive cultures. Like egyptians, greeks etc. They still had gods around, who protected them, punished them, rulled them. These primitive cultures builded pyramides(about which we still don't know, how did they build it->maybe they weren't as much primitive), collosseum and other buildings, that have lasted here for thousands years. Just take a look at that old house not so far from your home, builded by modern cultures. He's been there maybe about 50 years and it's almost so ruined as it's never been there.

Still when you learn about jews or about muslims, you are NEVER told, their God was developed by primitive people, who couldn't explain lightning, so they "created" a god in their mind. In fact, there are teachers saying, that "our" God (i mean.. I am from country with solid catholic tradition) created this world and that if we do something wrong, we go to hell. Lot of teachers use God as actual argument, when they preach a bad pupil.

It's really unfair, that children are teached, that egyptian gods are a mere human excuse for not knowing everything, however christian god, or muslim god, they're okey, noone will ever tell you, they are here just to explain, what we couldn't. But what does make a difference between christian god and egyptian gods? Why is christian god more probable to exist, than those gods from egypt, india, rome... Why is christian god never treated like fairy tale, while slavic gods are always treated like gentile in every history book?

When you face a christian, try to ask him. Try to get actual arguments from him, not just something like: It's obvious, that "our" God is the right one. You would be surprised, how this works on christians.
