"If you say you are not sure if it exists or not, isn't it dumb?"
Okay, right off the bat, I am not sure what 'it' is referring to. I would assume it would be this 'gidi gidi' thing you created, but when reading the entire second paragraph, it seems like it would rather refer to 'God.' If that is the case, what was the point of that whole first paragraph about 'gidi gidi?' Next, I'm pretty sure the second 'it' doesn't refer to God (which I believe the previous one and next two are referring to), which is really confusing. If 'it' DOES refer to God, then the English doesn't really make sense (why would me being ambivalent on the existence of God make God dumb?). Assuming it doesn't refer to God, what IS dumb? Agnosticism? Or the debate over God's existence in any form? It is not clear what is being referred to by the 'it.'
"You can be sure it's not, because i made it up?"
Firstly, this sentence in context doesn't make any sense. It doesn't not flow from the last sentence to this one (mostly due to the shitty sentence structure). Secondly, I don't know what the first 'it' is supposed to not be... being, Are we continuing from the last sentence, is this part supposed to mean, 'you can be sure it's not [dumb]?' Well, as I said before, I'm not sure this 'it' and the last actually refer to the same thing. If they do, it would make the first sentence not make sense, and if they don't refer to the same thing, then this makes even less sense.
"And because it happened in ancient times, does it mean that God is acceptable?"
Another 'it' with no clear context surrounding it, and this time it is surely incorrect to use 'it' because 'God' can not be substituted into the sentence! Assuming this 'it' refers to 'the creation of God,' the sentence is understandable, even if it still isn't structurally correct (which, to be clear, it isn't).
There, I typed a 1000-word essay correcting your shitty fucking English. It's honestly so bad that I can't even figure out what you MEANT to portray with your words. Stick to kebab language.
