Where did the Big Bang Come from?

Also if you look at the elements available on earth most elements up to iron are quiet common, while heavier elements become rarer , which is a result of heavier elements needing more energy(/more captured neutrons) to be produced. The very heavy ones come from supernovae where theres plenty of energy available. 

 

Not exactly the case, Uranium is one of the highest elements found on the Periodic table, and yet it is just as commonly found around the planit as Tin or Zinc.

Which begs the question "how did so much Uranium get here through fusion?"  It is simply hard to believe that fusion could have created each and every element on the periodic table, and then some how a star exploded all of thoese elements onto earth.

For the solarsystem look at: http://en.wikipedia.org/wiki/Abundance_of_the_chemical_elements#mediaviewer/File:SolarSystemAbundances.png

So generally the trend goes like "The heavier the element the rarer", but with some fluctuation because some elements are more stable than others and also it depends on how much of the lower weight elements are still not fused when a star dies. 

But yes i admit that there's more uranium on earth than i thought.

Nevertheless, the baseline message stays the same: The production of elements heavier than iron is no mystery!
