This is an answer I wrote for a question on a WikiQuestion
Space is just nothingness. There is no need to create a space. Everything has to be existed from without a beginning!
You cannot find a beginning of everything. It is not the right question. All the problems start when you look at the question in the wrong way.
Time as a measurement is just a concept. It is perceived through the changes of matter. If there is no change in the matter there is no need for a concept called time. The nature of changing is universal and so does the time. There is no beginning. It is hard to understand when you are so stick to the belief of a concept called time.
Some say it is the big bang. But all the theories about the beginning have gone very wrong that they have not correctly understood the question.
The questions of beginning have so tied up with the concept of time. Time is just a concept perceived by the changes. There is no universal thing called time. It is only this moment from beginning to end. Only this moment is existent.
Live in this moment and there will be no problem for you about the beginning.
