O Timothy! Guard what was committed to your trust, avoiding the profane and idle babblings and contradictions of what is falsely called knowledge—by professing it some have strayed concerning the faith. Grace be with you. Amen.
(1 Timothy 6:20-21) NKJV
Pseudoscientific stupidity can be quite breathtaking. What you call science we call pseudoscience because nothing in this video is a testable hypothesis. It’s pure narrative.
Prototaxites is a genus of terrestrial fossil organisms dating from the Late Silurian until the Late Devonian periods, approximately 420 to 370 million years ago. Prototaxites formed large trunk-like structures up to 1 metre (3 ft) wide, reaching 8 metres (26 ft) in height, made up of interwoven tubes around 50 micrometres (0.0020 in) in diameter. Whilst traditionally very difficult to assign to an extant group of organisms, current opinion suggests a fungal placement for the genus. Recent discovery of what are likely algal symbionts makes it a lichen, rather than a fungus in the strict sense. Lichens are classified with the fungal not the algal component, and the main tubular cells of Prototaxites are most like those of the fungal phylum Glomeromycota.

Prototaxites was originally believed to be a Yew tree infected with a fungus but over time it’s been reclassified as either a fungus or a brown algae type organism.
The thing that’s odd is that it’s the size of a Yew tree but has internal structure like a mushroom.
It couldn’t have lived on land.
In spite of its name, which suggests Gymnosperm affinities, Prototaxites has turned out to be a colossal fossil enigma.

We believe that Prototaxites lived in the aquatic zero-G environment of the first day, and it was deposited in sediment at the creation of gravity on the second day. It should be attributed to the Precambrian.
