For everything, like man, that has a beginning in time, there can be only three ways of trying to explain how it came to be.
1) Either, it was made, or created, or caused by nothing at all. In other words, it came out of nothing.
2) Or, it created itself.
3) Or, it has a creator, cause, or maker outside itself.
The first and second explanations are obviously impossible. It is inconceivable for something that has a beginning in time to come out of or be made of nothing at all. It is also inconceivable that it should bring itself into being. The universe and all that is in it, therefore, could not have created itself nor did it come about by chance. The conclusion then is clear. The universe and all that is in it owe its existence to a Creator or Maker outside itself. You, as a human being, as part of the universe, owe your existence to such a Creator.
To say, as many do, that human beings came from or evolved from other creatures or that they originated from water, or that there was a big bang and everything just happened to fall in place, does not really answer the question about the origin of the universe and all that is in it, including human beings.
