I believe there could have been a cosmic, visible, and audible "coming into existence." Why not? And since God has always been Creator, He might have "sparked" this explosion millions of years before. In fact, that's why there has to be so big a range of "uncertainty" in the timing of the "Big Bang" - 10 to 20 billion years ago. But that may be only what science is able to guess at right now.

Another "Big Bang" mentioned
The Bible says, "Our God shall come, and shall not keep silence: a fire shall devour before him, and it shall be very tempestuous round about him." (Psalm 50:3, KJV). That makes me think of another "bang". If you start thinking of what is called the "Second Coming" that is it.

The Bible says that Jesus promised that He would come back to earth (See John 14:3). This event has been called the Second Coming. It is what Christians look forward to. Some talk about the rapture, but whatever you call that which is framed in that promise, it will be a "Bang" - another bang! Just take a look at this:

"For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first. After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever." (1 Thessalonians 4:16,17)

Associated with this loud event is the waking of the dead! This will be another non-destructive bang. Here's another indication an audible event:

"But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up." (2 Peter 3:10, KJV)
