Elon Musk called Burning Man the 'best art on Earth' before thousands of mud-soaked attendees fled the disastrous event

• Elon Musk called Burning Man the "best art on Earth" despite chaotic weather conditions.
• The Nevada arts festival was hit with heavy rainfall, which turned the site into a muddy swamp.
• Organizers began to let stranded festivalgoers leave the site at around 2 p.m. local time Monday.

Burning Man may have been a partial washout this year, but that hasn't stopped at least one of its high-profile fans from singing its praises.
