Higgs boson was created in 2011.
The Higgs Boson is called the "God" particle because it would help explain on of physics biggest mysteries: how gravity works. Can both God and the Higgs Boson exist? Yes, if God exists, then he could have created the Higgs Boson, like he created other particles.
The "Higgs Field".
Higgs from America & Bose from India.
the Higgs Boson

The facility that found the most unambiguous evidence for the reality of the Higgs Boson is CERN.
It is a boson, a type of particle, that is a part of the Higgs mechanism, a theory of how particles can have mass if they are just energy
Quarks are point-like particles found mainly in baryons, mesons etc. The Higgs boson is a primary particle produced when the higgs field is excited
The Higgs boson, is well, a boson. All bosons follow Bose-Einstein statistics and are therefore CAN occupy the same quantum state (as opposed to fermions, i.e. matter, which cannot.) So basically, no. The Higgs boson does not occupy any space.
We are not sure if the theorized Higgs boson is real or not. If it is, it would be provide some support to ideas about what mass (and, therefore, gravity, which is associated mass) really is. We're still looking for experimental support that the Higgs boson is real, and now that the Large Hadron Collider is up and running, all (interested) eyes are on CERN and awaiting results.
Better question is when
A summary explanation of the Higgs Field is that it is an energy field that is accompanied by the Higgs Boson.
