How does the existence of humans on earth compare with the duration of geological time?

Here's an example to demonstrate the length of time that human beings have existed when compared to the time from Earth's formation:
Observe the length of your arm from your shoulder to your fingertips. This will represent geologic time; the time from the formation of the Earth. Run a fingernail file across the end of the fingernail of your longest finger. You have just erased the period of time in which Homo sapiens has existed.

How do geological and human time scales differ?
The geological time scale is hugely larger than the human time scale. For humans, a decade is a significant period of time, and even our civilizations span only a few thousand years... whereas in geological terms even a million years isn't that much.
Why is the geological column considered to be evidence for evolution?
In itself, it isn't. The geological column is a principle used in the preliminary dating of geological features relative to other features. Palaeontology uses estimates gained through geological dating to establish timeframes for the emergence of particular forms in the fossil record. These timeframes in themselves also aren't evidence for common descent, in themselves. What is evidence for common descent is that derived forms are almost always found in geological features that are younger than the layers the oldest basal forms are found in. For example: no primates before mammals; no apes before primates; no humans before apes; and so on.
Who discovered cyclones?
Nobody in particular discovered them. Cyclones have been affecting humans through their entire existence. Gradually, through scientific discovery we have come to understand them.
What does not cause erosion?
There are many things which cause erosion, and far more which don't. Compare your question to: "How many animals on earth are not chickens?". I can speculate as to what you mean, and provide a specific list of potential answers, speaking in Geological terms:Factors which do not directly contribute to erosion like the Sun and Moon.Weathering, including humans, plants and animals, does not affect erosionGravity (though this may also be indirectly related)Tectonic activitySedimentary processesMetamorphismGlobal warming (though this may be indirectly related)I hope this short list helps to answer your question.
