Life on Earth

It has been argued that evolution cannot explain the development of life on Earth. Often it is suggested that life came to Earth from another star system (panspermia), but that only removes the origin of life by one level. It would only take one pair of molecules which, when combined, would be able to reproduce, or cause to be reproduced, another pair capable of the same thing. After that, time would produce the rest. Considering the Quattuorvigintillion atoms on the Earth, and the Quattuordecillion molecules on the Earth, the possible interactions and random combinations would have been beyond comprehension.

Consider that Earth offered of a laboratory consisting of over 328,000,000 cubic miles of ocean, and more than 2,000,000 cubic miles of fresh water. In addition, that laboratory consisted of an additional 26,000,000,000 cubic miles of soil “capable” of harboring some form of life. This laboratory had hundreds of millions of years to proceed towards even the most primitive form of life, and billions of years to perfect it. It is no wonder at all that we have not yet been able to duplicate that feet with only a few cubic meters of water over a time span of dozens of years.

Perspective. Given that a quart is about the average test volume used to attempt to duplicate life, the oceans alone would contain 273,600,000,000,000,000 quarts of water. (give or take a few gallons).

It seems this post assumes the abiogenesis origin of life on earth. Q: Is the abiogenesis of life on earth a scientific law and is that law as well attested as Newton's law of gravity or the heliocentric solar system? The scientific method requires the theory to be testable - and falsifiable too. That is why we do not teach the geocentric astronomy today.

Since the only two options are abiogenesis on Earth, or abiogenesis via panspermia, I merely proposed a plausible explanation for how the former would be a reasonably high probability. Of course, the same conditions would be applicable to life being formed somewhere else, in a similar environment, and brought here.

Since there is no way to verify or refute this proposed explanation, there is no need to hammer it with requirements for scientific method or testability.

Glad you clarified this, thanks.

Maybe an alien probe 4.6 billion years ago landed on earth and sent back images and science of a dead rock.
Like us they couldn't guarantee probes would be 100% sterile and a few bacteria survived the trip.

We have done the same on probes at Mars, Venus and Titan.

Yet another option to spread life around the galaxy.

Interesting option here. Currently we have 4142 exoplanets confirmed, The Extrasolar Planets Encyclopaedia

In your option offered, do you know which of the 4142 exoplanets the *alien probe* came from, 4.6 billion years ago? Attempting to apply a more rigorous scientific method to the model used to explain the origin of life on Earth.
