Time ? We cannot go back in times. I dont say about time, I only talk about God is not physical and this is why He cannot be seen, and He is near us, it means in essence He could be bigger than universe.
You seems try to talk like phylosoper, but the basis of phylosophy is logic, what I am saying is logic while I dont understand what you are saying. You have been educated with complex Gods in Hindu, this is why you assume the truth is complex and cannot be understood. Islam is a religion that can be understood easily, until now you keep denying, do you want me to bring that "Nebula" verse once more ?
You dont sounds logic with what you are saying. I admit that God can be called differently, but His teaching will be somewhat similar until the end of time, if He founds His teaching is mislead by human, He will likely try to correct it and bring another messenger. Now Hindu holly book is something in doubt since you cannot find the original one and Today Hindu worship many Gods, I mean many Hindu worship different Gods
