Technically it would be heavier.
Think about it, evolution created animals and mammals which started out as single-cell organisms when Chuck Norris first created Earth.
7.5-10 Billions Humans, and I can't be assed to count the Animals, but that's a lot of weight combined.
Of-course if you're talking about the gravity weight...

Then there is no change at all as the Earth isn't physically acting on anything, it's just floating in the Solar System.
