"Trees are composed by 90% gasses, prevalently H2."
This is my statement and it's based on exactly 0 evidence and I just felt like making it up, but you don't know it. You think I'm serious and convinced about it and you have to change my mind.
Now try to object this statement with fakts, lojic and evidenkes and find the truth, but you can't use any resource on the matter that's from the internet, you can rely only on yourselves.
Have fun.
