These are english subtitles (I made) to the czech web show "New Planet", a 6-episode show animated in 2008 almost entirely in Paint by one man, Matěj Mádr. It has an overarching story, so you should watch them in order.
You can watch all the episodes here (higher quality) or here (lower quality).
Episode list:
1 - We Are Not Alone
2 - First Day On Pars
3 - The Nasty Green Goo
4 - Satan Is Not a Satanist
5 - The Spray
6 - The End

The creator also made a show before this, "Srandovi". It is a light parody of the Simpsons. There were 16 episodes, but most are lost. Three are saved - 1, 2, 3. If you want me to translate those too, message me or email me.
