What is the most reliable evidence in understanding the origin of life?
- The earliest evidence for life on Earth incorporates biogenic graphite found in 3.7 billion-year-old metasedimentary rocks from Western Greenland and microbial mat fossils found in 3.48 billion-year-old sandstone from Western Australia. All the more as of late, in 2015, "stays of biotic life " were found in 4.1 billion-year-old rocks in Western Australia. Life is a trademark that recognizes actual elements that have natural cycles, like flagging and self-supporting cycles, from those that don't, either in light of the fact that such capacities have stopped (they have passed on) or on the grounds that they never had such capacities and are delegated lifeless. Different types of life exist, like plants, creatures, parasites, protists, archaea, and microorganisms.
We know that life began at least 3.5 billion years ago, because that is the age of the oldest rocks with fossil evidence of life on earth. These rocks are rare because subsequent geologic processes have reshaped the surface of our planet, often destroying older rocks while making new ones.
