Bill Maher was not into the big Mars news when it came out. Then Neil deGrasse Tyson came along.

On Friday’s “Real Time,” Maher explained deGrasse Tyson actually convinced him that the discovery of water on Mars was extremely important.

“I’m admitting, you know, I changed my mind,” Maher said before deGrasse Tyson went into his “spiel” about how many important discoveries like atoms and electricity were also written off at first and how life on Earth could’ve possibly been “seeded” from Mars.

More importantly, the scientist also says there is ice at the poles of Mars, prompting Maher to ask the most vital question, “So they might have room service?”

“Possibly,” deGrasse Tyson laughed.

“Real Time with Bill Maher” airs Friday at 10 p.m. ET on HBO.
