What life forms existed first on Earth?
As the Bible is a letter from God and beneficial for our teaching and setting things straight according to 2 Timothy 3: 16,17, my answer will be in reference with what the Bible has to say concerning the first forms of life on earth. We all have to admit that our world is filled with so many marvelous things. Big things, like a setting sun that turns the western sky into a blaze of colours, little things, like a tiny bird, a warbler, flying high over the Atlantic, heading towards Africa on its way to South America, ingenious things, such as bats that use sonar, and simple things, that we often take for granted, such as a smile, a touch of a hand, a kind word, and so forth, which is what our world is all about. The Genesis's account deserves at least a fair hearing to see whether it harmonizes with known facts and also to remember that the Book of Genesis was not written to show us "how" of creation but rather covers major events in a progressive way, describing what things were formed, the order in which they were formed and the time interval, or "day or period", in which each first appeared. I suggest you read whole chapter of Genesis 1. But to answer your question which is: " What life from existed first on earth? Genesis 1: 1- 30 has this to say: " God first devided light from darkness, then devided watres from dry land and then caused grass sprout, seed-bearing plants and fruit treees according to their kind. Then the water swans were filled with living creatures , the sky was filled with flying creatures. and earth was filled with wild animal and domestic animals according to their kinds. Genesi 2: 7 reads. " And Jehovah God went on to form the man out of dust from the ground. The roots of the word " human" comes from the word "dust". The answer to your question is: "Grass sprout and seed-bearing plants"
