Most probably there's a drive to giantism built into life.

However note that there are also mass extinctions due to impacts that
can and have destroyed all large lifeforms.

Between impacts, size tends to increase.  However *at* the impacts,
size decreases - often dramatically.

Despite such impacts, it is thought that the largest living creature
is one that is alive today.
