Ancient giant silicon-based tree hypothesis

The ancient giant silicon-based tree hypothesis was first formulated by Russian YouTuber and conspiracy theorist Ludin Rusi (Людин РɣсиIt's a pseudonym, not an actual name. Translates as "person of Rus'" in what seems to be an attempt at ancient Russian.) in 2016, which proposes that many geological formations are actually remains of an extinct clade of huge botanical species.There are no forests on Flat Earth Wake Up. YouTube. 1 August 2016.Flat earth supporter claims mountains are the ancient remains of gigantic silicon trees. Ufoholic. 12 August 2016. Supposedly, gigantic trees of the past are so large that in comparison "there are no forests" today. Rusi tied his message to Flat Earther views (though the connection isn't obvious), and part of that crowd have become drawn to the idea. Believers may differ in whether they view all or merely many mountains as being the remnants of ancient gigantic plants.
==Origins==
It's another example of Biblical literalists trying to reconcile their beliefs with reality.Kyle Hunt. Were There Giant Trees in the Days of Yore?. Renegade Tribune. 10 August 2016. However, trees that are both giant and made out of rock is not mentioned. Furthermore, it does not account for the living state of those trees before they turned into stone upon dying.
==Scientific objections==
===Silicon biochemistry===
Silicon life, even if possible, would not be compatible with carbon-based life. Due to its bigger size, silicon atoms can hardly establish double bonds, as carbon can. As a result, many silicon analogs of carbon cannot form,Raymond Dessy. Could silicon be the basis for alien life forms, just as carbon is on Earth?. Scientific American. making its chemistry much poorer than that of carbon, which illustrates greater molecular stability, and therefore the independence of carbon analogs, that isn't vulnerable to contamination with cross-reactants ever abundant in the case of carbon.
It is also dubious if aerobic respiration could be possible. Both carbon and silicon have a valence of +4 but oxidize differently. Carbon's smaller atomic size lets it form stable double bonds with oxygen, and the resulting CO2 is a gas. Silicon is too large to form stable double bonds and forms single bonds with four oxygen atoms, leaving the oxygen atoms to bond with another silicon atom. This atom bonds with three other oxygen atoms, which all bond with silicon, and so on ad infinitum as a crystal.
===Structural problems===
Earth's gravity posits biophysical limits to plant growth.Niklas KJ. Maximum plant height and the biophysical factors that limit it. Tree Physiology. NCBI. 27 March 2007. George Koch et al. of the Northern Arizona University calculated that at most, trees can theoretically reach a height of 130 meters.How tall can trees grow?. LiveScience. 17 June 2011. There is no evidence that trees with fantastical biochemistry could grow any taller than that. However, it does not consider whether or not gravity exhibits properties instead of them coming solely from density and buoyancy variations.
==Things we can praise it for==
The author did at least have the awareness to call his idea a hypothesis and not a theory.
