Did NBC reporters Chuck Todd and Sam Brock low key admit to the extraterrestrial hypothesis being the most likely?

It’s in the Part 2 of 2 NBC UFO Report video already posted . They admit beginning their investigation as debunkers and ending it quite different. After 1:41, they go into their own opinions on it, and the wording is quite interesting IMO. Chuck: “we can’t prove another theory yet” Sam: “we don’t have it”
