  We explore the Dirac spin liquid (DSL) as a candidate for the ground state of
the Mott insulating phase of fermions with six flavors on the Kagome lattice,
particularly focusing on realizations using $^{173}$Yb atoms in optical
lattices.
  Using mean-field theory and variational Monte Carlo (VMC) simulations, we
confirm the stability of the DSL against local perturbations of the Dirac spin
liquid ansatz within a 12-site unit cell and against small second-nearest
neighbor and ring exchange interactions.
  To characterize the DSL, we calculate the static and dynamic structure factor
of the Gutzwiller projected wavefunction and compare it with mean-field
calculations.
  The static structure factor shows triangular-shaped plateaus around the $K$
points in the extended Brillouin zone, with small peaks at the corners of these
plateaus.
  The dynamical structure factor consists of a gapless continuum of
fractionalized excitations.
  Our study also presents several complementary results, including bounds for
the ground state energy, methods for calculating three-site ring exchange
expectations in the projective mean field, the boundary of ferromagnetic
states, and the non-topological nature of flat bands in the DSL band structure.
