    Since God created the universe and it didn’t evolve, this guy is simply creating imaginary simulations of an imaginary past that never happened. Totally useless.

      Pretty sure that God set up laws -like gravitational attraction and centrifugal force for example- to govern how things work in our universe. All religions seem to agree that He is a being of laws. Why is it “useless” for us to pursue understanding those laws? It’s not like scientists are just pulling this stuff from their butts, we have hundreds of years of methodic observation of the stars – the last 100 of which have given us not just a good understanding of how our universe works, but also given us several technologies that benefit us daily.

      You need to reevaluate what you think the scriptures say about the creation as none of them – not the islamic, nor the Christian, nor any other – offer any specifics on HOW God did what He did. By His Word, or by His command, He made things happen. Things formed. But We aren’t told what the process entailed, nor the length of “time” taken (what does “six days” in Christian or Islamic belief mean to God anyway?), nor are we commanded to be ignorant.

      Science is cool man, and it doesn’t write God out of existence. Just because some blow hard scientists say God isn’t real doesn’t mean their work does too. If you think it does, you haven’t payed enough attention.

        Actually, six days means six ordinary 24 hour days. I’m currently reading Dr. Jonathan Sarfati’s book The Genesis Account, which very clearly shows from scripture and science and history that six days means just that. Scripture is very clear on what it means. And all evidence affirms it.

        It’s useless to pursue ideas that assume there is no God. The big bang and cosmic evolution (i.e. star formation, galaxy formation, etc.) all depend on there being no God. I believe studying the universe is awesome, but not when most of what is paraded as fact are just circular reasoning arguments that assume they are right to begin with.

        You are right we are not commanded to be ignorant. What you don’t realize is that your position is an ignorant one. The truth of the universe is very different from what secular scientists claim and what you’ve obviously accepted as fact.
