Hello. I love good weather all thanks to the sun! It is a perfect sphere of hot plasma! 
gpt
*takes a step forward* Me too. I saw that the sun is actually really white.
human
Yes you're correct but it only appears yellow because of atmospheric scattering.
gpt
*takes a step back* Very cool. Did you know a lightening bolt is actually 5 times hotter than the surface of the sun?
human
*takes a step back* I hope I never get struck by one! Surprisingly the sun is only 1 billionth the size of the biggest star in our galaxy.
gpt
Me either lol. That's pretty small then in comparison to the other stars. I would have never imagined that.
human
*takes a step forward* Yes me too. The sun is definitely the most important source of energy for life on earth. It accounts for about 99.86% of the total mass of the solar system.
gpt
Definitely. It produces enough energy in one second to meet the needs of our planet for 500,000 years which is amazing.
human
That is so cool. It makes sense though since the mass of the sun is about 330,000 times that of earth.
gpt
For sure. Do you like animals?
human
Yes I love animals. There have been around 1.5 million species described, so plenty for everyone to have a favorite!
gpt
That's a lot of species. I saw there are 20 quintillion animals on Earth.
human
*opens mouth slightly* That is amazing and I can't even fathom that much. The study of animals is called zoology and they must be busy with all those animals!
gpt
*eyes widen* For sure. Animals get white patches on their heads when they are domesticated.
human
*lips slightly parted* Oh maybe that explains why there are so many white patches on dogs. If you are annoyed when you get hiccups just remember they are a hold over from early evolution.
gpt
*takes a step back* Definitely. That's interesting about hiccups. That would have been so cool to have lungs and gills.
human
Yes I would love to breathe underwater. The country of Scotland has a protection act against the Loch Ness monster. Do you think it exists?
gpt
*opens mouth slightly* That would be awesome to breathe underwater. That's hilarious for something that might not even exist. 
human
Yes I think so too. And this happened all in 1912! Well it was great chatting with you.
gpt
*eyes brighten* Animals are pretty fascinating to study. It was good chatting with you too!
