It's an intuition or speculation at this point. The only major evidence we have is that a logarithmic graph of information vs time in evolution seems to cut off abruptly at the age of the Earth, suggesting that the process started before Earth if a constant rate is assumed. https://dailygalaxy.com/2018/09/moores-law-life-is-older-than-earth-itself-a-process-that-began-billions-of-years-before-the-formation-of-our-solar-system/ https://dailygalaxy.com/2018/09/moores-law-life-is-older-tha... This is definitely not conclusive as it could also mean that some other process with a different rate or probability structure started life. You can't always just do a regression and draw a line and assume that it holds for all time, as many startups discover. ;) We also know that organic molecules are ubiquitous in the universe, so there's that too.
