Do we know what type of organism first started life on Earth?

AI Thread Summary
The discussion centers on identifying the first type of organism that started life on Earth. Participants mention that algae might be one of the earliest forms of life following the volcanic period and the onset of rain. Key concepts introduced include the PAH world hypothesis, the RNA world hypothesis, and the role of archaea in early life. These concepts suggest that simple organic compounds and RNA could have played significant roles in the origins of life. Understanding these early organisms is crucial for studying the evolution of life on Earth.

I am not sure on this, so hope someone can shed some light on this.

What type of organism was thought to be among the first on earth? I am not sure if this is the right way to ask this :)

Lets say if I wanted to see, or do tests on an organism, and my tests were related to doing tests on the first organism on earth, or the first life on earth, what would it be?

For some reason I thought algee was among the first on Earth after the heavy volcanic period, and when it started to first rain.

Thanks guys!

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
