The Raindrop..... From 2.7 Billion Years Ago!!!!
In Africa, a raindrop fell. Seems normal right? What is scientists found the remains of a 2.7 billion year old raindrop. Impressive. The raindrop fell in South Africa while the Earth was still growing. The weird thing: 2.7 billion years ago the earth should have been dimmer than it is now. However, this supports that the Earth either had greenhouse gasses or a different atmospheric pressure. In current times, fat rain would fall 30 feet a second. Before, if the rain had a thicker atmospheric pressure, it would have fallen slower, resulting in asmaller mark in the earth.
I believe that the discovery of the raindrop is a huge way of understanding how the Earth was like 2.7 billion years ago. One reason is because humans don't show prior, necessary knowledge on how the Earth was like before our time. The second reason is because this might help us discover if life could be on other planets as well. The final reason is because this might affect later like. Who knows? If the atmosphere changes drastically again, we might need to know what to expect from Mother Nature. All in all, I believe this discovery has impacted human understanding and will help us understand about the past and the future. I have enjoyed reading this article and I believe this will help for later times.
