First of all, EldritchCellar (EC) is right.  I've seen a lot of worse.  I personally spell everything correctly but my nemesis is the missing word.  I think it in my head but somehow it gets lost between here and the keyboard.  Rest assurured I know exactly what you meant to write and it's a nice origin.  A bit derivative but no more than anyone else's origin. Peter Parker was bitten by a radioactive spider, the Fantastic Four was in an accident in space, Barry Allen was accidently doused with chemicals at the same time as a lightning bolt strike.  They are all accidents or an unintended happenstance of incredible odds.  What are the odds that a planet is going to blow itself up but a civilization that is advanced beyond reckoning, even to the point of having space colonies like Argo City would decide "Naw, our leading scientist is full of it.  Yes we have space colonies but we won't keep a couple of ships handy just in case."

Really?

Yet that gave us the most popular Super-Hero of all time.  Origins are reworked over the years to fill in huge plot holes, like the fact it would take 4.3 light years or approximately 165,000 years by an non-warped rocket ship to reach the nearest star from Earth.  Krypton is supposedly beyond that.  He's had his powers since the day he arrived then magically they didn't manifest for years as his cells soaked up solar radiation.  Every hero besides Batman has had a change in canon as if they became inconvenient truths.  Really, just give us some plausible deniability and we'll buy it because we want to.  If they don't like the origin or feel the hero has run his course, they give us a new hero to pick up the banner.  It's okay.  A superman that over 70 years old won't do, even less likely for Batman.

It's what that hero does with his gifts or mutation that really makes the hero.  That and a hero is only as good as his Villain.  You don't have to give us anymore until it's time for the origin issue or even the first issue.  Superman didn't get an origin until almost 20 years after he was introduced.

I think the reason Marvel turned you down was a terrible reason.  Neal Adams drew Archie before he drew Batman and is without question one of the greatest comic book artists of all time.  The same with Frank Frazetta.  Before he gave us those iconic Conan paintings, he drew Lil Abner.  It would've been better to take you in and then ease you into the rotation.  I would've jumped at the chance to just be an inker!
