I look at it like this. Ants make up 15–25% of the terrestrial animal biomass. More than 12,500 out of an estimated total of 22,000 species have been classified. That's a lot of fricking ants here on Earth. To the ant, Earth if enormous and the number of ants that have come into contact with humans is minuscule. Humans are the ant. What we have seen and can do is minuscule when you compare it to the grand scheme of things. IMHO.
