"God Exists (Atheists get owned)"
He has very good points.

I would say this, if bacteria had self-awareness, they would most probably think there is no species greater than those on bacterial level -- after all nobody found anyone higher yet, and many would argue about absence of evidence and how it doesn't prove this or that. Bacterial science would also confirm that nothing greater than bacteria ever evolved, and argue with those delusional individuals who still believe how a giant blob in the sky created everything, who goes by many names, like Blobovah, BLOBWH, or the Merciful and Compassionate Blobbah. Believers would of course fear eternal damnation if they break one of the commandments supposedly dictated by this friend in the sky, commandments not much different from other bacteria-made laws of that time.
Living inside a human body, which is their Universe, more skeptical individuals would say it was not really created by BLOBWH, because science clearly shows how all matter was created randomly, combining itself on its own over lengthy periods of time. How is this done, and how could randomly spinning matter create trillions of galaxies, they wouldn't be really able to explain. Most probably taking refuge in that old circular logic argument about absence of evidence, just like the true believers who like to use the Holy Untouchable Book to prove BLOBWH actually exists.
This is how much they would know about our environment and human nature, about our mental capabilities, dreams and desires. This is how much we know about our Universe and its architects.
