Timeline reflection

One of the most important event in Earth's history if not the most important event was the beginning of life on earth. While scientist are unsure how life was initially formed, it is still undoubted one of the most important events, in earth's history for a couple of reasons. First, it was an extremely unlikely event, and was very complex. For that reason knowing how life first formed would be very helpful to understanding how we got to where we are, and how likely it is that life exists in other place in the universe. The other reason is that the first life, whatever it was, was the beginning of every living thing that exists, without that beginning no life would exist.

Another very important event in earth's history is the Cambrian explosion. It was during this event that life became more diverse. This event is important because it was the event that created diversity in life. During this event nearly all of the major groups of animals began to appear. It was this rapid diversification that led to the creation of many of the species that currently exist.

Another major event in Earth was when life first went onto land. This was also very important, because it was the beginning on life moving out from the oceans, and spreading out through the entirety of earth. This also marked the beginning of a huge new section of earth's history. It created a whole new place for life to expand, and evolve. This event is responsible from a lot of the diversity we see on this planet.

I was really surprised by how long life has been on earth, and that despite that, it was very simple for a very long time, and then is suddenly shot up in a relatively short period of time. It was also interesting to think about how huge Earth's history is, and that everything that we ware taught in our history classes are only a tiny portion of that history. It also profound to me that despite only having existed for a very short time humans have affected the planet so much. It is very weird to think that what took nature such a long time to create has been dramatically changed so quickly. The one question I still how is how did life first get formed?
