One of the main answers is based upon the so-called RNA world concept which was formulated by molecular biology pioneer Walter Gilbert in 1986. The origin of life on Earth has to be one of the most engrossing queries out there and also equally significant.

Miller working in the laboratory of harold c. Earth formed about 45 billion years ago abbreviated as Ga for gigaannum and evidence suggests that life emerged prior to 37 Ga. Because as important as the origin of the Universe and its constituents is it is.

Tiny zircons zirconium silicate crystals found in ancient stream deposits indicate that Earth developed continents and water -- perhaps even oceans and environments in which microbial life could emerge -- 43 billion to 44 billion years ago remarkably soon after our planet formed. So how could life have arisen on Earth around 38 billion years ago. In deconstructing cell structure from the viewpoint.

The Big Bang Theory is the most accepted theory regarding the origin of the planet. The Beginning of Cellular Life on Planet Earth A Possible Structure for a Primitive Cell- Biology Libre Texts. 377 billion years agoThe earliest time that life forms first appeared on Earth is at least 377 billion years ago possibly as early as 428 billion years or even 441 billion yearsnot long after the oceans formed 45 billion years ago and after the formation of the Earth 454 billion years ago.

According to the hypothesis nucleotides the fundamental building blocks of the nucleic acids A C G and U arose from the primordial soup and short RNA molecules were produced from the nucleotides.

In the flask at the bottom he created an ocean of water which he heated forcing. These rocks are rare because subsequent geologic processes have reshaped the surface of our planet often destroying older rocks while making new ones.
