Humans do actually control the planet last time i checked, we control animal populations, forestry, fish stocks, we can dam and divert rivers, we can decimate or propagate the planet as we please, we can even make it rain... But if you agree with that but are arguing we can't change the gas composition of the atmosphere your are also wrong.
We even have Mars in our sights now, we are no longer a group of a couple of hundred thousand cavemen anymore encase you noticed.
