Using real science that is unknown and using current knowledge and the basic laws of the universe it is currently unknowable.<quoted text>
Using real science how did everything come onto being.
There is nothing to say that the visible universe was created from anything or nothing. The very laws that describe our understanding of universe we inhabit did not begin exist until 10^-34th of a second after the event.
Science and mathematics are working on expanding our knowledge and several theories have been introduced based on the mathematics of Dr Param Singh, at least one of those theories explains ALL the anomalies we can see in the visible universe.
So, real science is busy working on the problem that you love to pose, a problem that science and most assuredly religion can not yet understand but you are of course welcome to make guesses and proclaim them as TRUTH because thats what your faith tells you to believe. The fact that this TRUTH is pure guesswork based on nothing but the superstitions of bronze age man seems to pass you by for some reason.
