Now that is a scary concept that hadn't occurred to me. That life is an unintentional side effect of the simulation. This goes to show that we do not have an inkling of the vastness of the laws of physics that have not yet been apprehended by humanity. So we know the laws of physics from, say, the year 1400 CE or the laws of physics from the year 2012 CE. But what will we learn new by 2030 or by 2050 or by 2100? Lots, I bet. Remember that in the year 2017 CE we did not know for sure that gravitational waves even actually existed. We were searching for them with sophisticated experiments and devices.

Having said that, I believe in my Roman Catholic faith. That God (The Most Holy Trinity) created us and our reality out of pure love for us. But the Holy Mother Church is open to almost all scientific endeavor and has no problem with scientific inquiry and understanding. God is big enough to take it ;)
