Best! Thank you so much for this video.

Thanks, this was very informational

Well this helps me in my online class in grade 7

These videos are getting alot of views because of our teachers🤧😂

I’m here from science class🥴✌🏼

hello mister osama

The best explanation i saw Thanks alot Can you explain how evolution is a theory?

This guy should be a teacher

Omg this video has ruined my life. First It took me on a cycle of bad thoughts and people making fun of me. But I continued watching otherwise my teacher would eat me. What I found were bad puns which resulted in me seeing a counsellor. The complicated explanation got me arguing with my wife over its meaning and not long after we got divorced. My son hates me and I have clinical depression. The poor animals getting eaten did it to me. I committed suicide on the 11th of October. Pls pls pls do not watch. -Ghost of a former happy person
