I'll repeat the question for those who may not have understood it. So
where is your data that shows that the mass of the Earth has increased?

Jeez, are you slow. Surface increased so volume increased. Then either
mass increased and gravity increased, or density increased and gravity
decreased.

Run that by me again?

Sure.

Surface increased then volume increased. Two possible explanations for a
volume increase:

1 - Volume increase is due to density decrease. But it means that
density was much higher in the past which means that gravity was also
much higher. That hypothesis is ruled out by the gigantism of past
fauna/flora.
2 - Volume increase is due to matter creation. It follows that gravity
changed with a rate depending on the density of created matter.

Considering d the average density and g the gravity at the surface, then
g=Gm/r^2=G.d.V/r^2=(G.d.4pi.r^3)/(3.r^2)=4/3.pi.d.G.r

It follows that if d remained approximatively constant, then the gravity
increased linearly with the radius of the planet.
