My understanding is light travels 6 million miles a year. So we are about 15.5 light years from El Sol. It is also my understanding that 15 is more than 4.37. while 4.37 X 6 is less than 93.
Light travels 6 million miles in approximately 35 seconds I think.
6 million miles / 186,000 miles per second (speed of light)

Ehh, no. A light year is (roughly) 6 trillion miles. We're nowhere near a lightyear away from the sun. It only takes light ~8ish minutes to travel from the sun to the earth, which is ~.000016 light years.
~4.37 ly to Alpha Centauri, ~.000016 ly to the sun. We're vastly, vastly closer to the sun.

Wait... What do you even mean by "el sol"? Because our Sun is like 8 light minutes away. I'm confused. If Alpha centauri were closer than the sun, we would have a huge ass second sun in the southern sky.

Light travels roughly 6 trillion miles per year. Alpha Centauri is ~250,000 times further away from Earth than the Sun.

Yep. By NASA light travels ~671 million miles per hour... waaaay faster than 6 million miles a year.

I recently finished reading "The Three Body Problem." Excellent hard science fiction for those so inclined.

I watched the Brazzers adaptation.
At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'

We're eight light minutes from the Sun.

I think it highly possible that you may be right. Big difference between 6 million and 6 trillion.
My only excuse is that in school my math teacher was arrested as a cell leader in the notorious al Gebra movement. Our classroom was littered with weapons of math instruction and I got taken out by a stealth bomber disguised as a pop quiz. It was terrible.
The god who allows children to be raped out of respect for the free will choice of the rapist, but punishes gay men for engaging in mutually consensual sex couldn't possibly be responsible for an intelligently designed universe.
