it's been asked a lot of times, god is not a 3dimension thing, we don't intrepret it as having a start and end, but u will probably continue the questions y can't the world don't have start and end, and only god can, that's was once my question too, it's a very hard and deep question to answer, in fact that's a book explaining it i think. but i can breifly explain it, when u ask where god come from, what answer do u expect, sth that creates it? then sth can create the creater of god? but then there must be a start, the very first, and who 's that very first? that's the god, the one that can be created can not be consider as god, then at the end result is just the same, there's god. if u said there don't have to be a start, it can go infinite, but then u will contradict with ur first thought where u ar assuming there's a start and end, or else i can just explain god has no start and end, which explains ur infinite situation, and lastly if u said y can't world have no start and no end, and only god can, that's becoz it's proved that this world, this universe has a start, it only happened after an explosion, including the dimension. this explosion i will explain later it's different from what u believe it is. this breifly proved there's no point asking where god came from, it proved god just happends to be here, no start, no end. It's a hard concept, u might don't even undertsand if u read that book that talks about it, but y ppl believe even they don't undertsand this concept, becoz we can prove that god exist in another way. It was said by some "jit hok ga", it's hard to prove that god exist, but it's harder to prove that god does not exist. you ar right now assuming god does not exist, and asking me to prove it, y not change ur way of thinking, now i assume god exist, prove me it doesn't, if u can't prove it, might as well tag along with it. My way of showing y god exists is to ask how this world come from, this is what make me believe now too. Seriously, how do u think this world come from? humans come from monkey? it's been disproved, there's no evolve as we have learned in bio, explosion in coincedence? this is what many ppl think, but sorry, it's disproved already it's said that it can't happen in coincidence becoz the chances is too low that it approaches 0, u might argue that there's still a chance, yes, there's a chance, but that will require an infinite amount of time, however, time is proved to be not infinite, well these stuff u just have to read those science theory, i am not the one who make the theory therefore explosion in coincidence is not possible, but u might heard from somewhere that this world came from explosion, yes, that's the explosion i talked about earlier, this explosion is referred to the creation of the world, in fact it only lasted milii....sec, it was caluclated somehow, which this is impossible for a normal collision of explosion, this explosion is referred to the creation of the world, when god creates it, everything suddenly popup, that's the explosion that ppl are talking about, not the coincidence one. and so, i have proved all the possibities that the world can come from, but all are disproved, and the only possible left is there is sth that creates it, which is god. you don't have to go into that deep yet, so far we just no that there's a god that creates the world, then that's enough for u to believe, asking where god come from became pointless becoz now u no god exist, then basically believe in god, by not knowing how god come from should not affect ur believe in his existence. like u believe i am in waterloo, but u don't no how did i arrive waterloo, that doesn't affect am i in waterloo or not, i am in waterloo, it's proven. just like god existence is proven here. there will be a lot of questions, i have a lot of questions myself, but the main point is do u believe it exist, and so far there's no proven statement that said god does not exist, and also by logic, if god does not exist, then this world won't be here. and so i no god exist, and so i believe, what u believe in is another question, but so far u just have to no that there's a god
