Of course you can't believe everything you see on tv or put all your faith into such things as crop circles, Loch Ness monster, etc.
And just because someone says "What if..." doesn't mean to say that they believe in the "what if..."
If the aliens did create us, they should realize by now we are sentient beings, and realize that WE know there is something going on here with all the UFO sightings and evidence...
Last year 9 UFOs flew over our city here, it was on the local news, they aren't making any effort to hide.
As a matter of manners they should either introduce themselves or make themselves scarce.
They could be humans of the future time travelling, for all we know.
