  I think the first element in the periodic table Helium probably came first because its the simplest.. but chemists out there would know better than me!

  Hydrogen and Helium were the first created (hydrogen is the simplest and then helium next). We don’t really know what was there a millisecond before the big bang happened. We assume that there was nothing except everything was concentrated in to a tiny but incredibly dense singularity (point), which then exploded!
