Earth is still divided among nation-states, though all are affiliated beneath the overarching banner of the Systems Alliance
The Systems Alliance is an independent supranational government representing the interests of humanity as a whole.

and
The Systems Alliance is the representative body of Earth and all human colonies in Citadel space

so would the Alliance fleet come to defend earth? yes, is it the one world government of Earth? no. does it have bases and a military pressence on/around Earth? stands to reason yes. why? it would be cheaper to have the SA base a security force at Earth than for Earths governments to try and set up ANOTHER multi-national military to protect earth and sol.
oh and you want proof of SoL/Earth based SA military bases? Base on the moon you go to in ME1.
the SA's primary mission is to represent Earth/humanity outside of sol both militarily and politically. this doesn't mean it doesn't have operational jurisdiction in Sol as you don't need to represent yourself in your own house.
oh and notice how in the pic at the top of the "Humanity and the Systems Alliance" entry is shepard (Alliance marine) in a ship (that is logically an alliance ship) orbiting, wait for it, Earth.
