Either everything came from nothing, or something has always existed. Do you have an alternative?
I believe that something has always existed. The Creator. Everything, as we are given to sense it with our five senses, was created by the Creator. If there was a Big Bang, it was His work. It may be a matter of terminology, but, for example, when FatherofFour posted “But the big bang, if it happened, is God’s creation. Something from nothing.” I agree with him on the first part, but disagree that it means “something from nothing”. I would argue that if the Big Bang is God’s creation then it is something from something (that something being God).
