Really? I have a question then. Where did the matter come from? That would have been the first questioned I would of asked in that class.
God created it
. I believe atheists have a different answer...
The Qur'an talks about the big bang:
"Moreover He comprehended in His design the sky, and it had been (as) smoke: He said to it and to the earth: 'Come ye together, willingly or unwillingly.' They said: 'We do come (together), in willing obedience.' So He completed them as seven firmaments in two Days, and He assigned to each heaven its duty and command. And We adorned the lower heaven with lights, and (provided it) with guard. Such is the Decree of (Him) the Exalted in Might, Full of Knowledge. (The Noble Quran, 41:11-12)"
"Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. Will they not then believe? (The Noble Quran, 21:30)"
How so? I would like to know
Especially since you can't really repeat it or record it like in a basic experiment (though the Big Bang is not very basic )
They go back and retrace the events that took place...and actually simulate the conditions so they can run tests and stuff
