As the release date for Blink-182's comeback LP, the band's first without founding guitarist Tom DeLonge, approaches, conversation surrounding the iconic pop-punk group has flourished. Today, it's Mic that decided to sit down with DeLonge, perhaps unintentionally revealing the real reason Tom is no longer part of the band he created.

The publication asks if focusing on aliens is the reason he left Blink, to which DeLonge replies:

"Well it's not so much about Blink. It's about what I'm doing with my life now. When you're an individual like me, dealing with something that's a national security issue, and you're being gifted with the opportunity to communicate something you've been passionate about your whole life—something that has the opportunity to change the world over time—being a small part of that is enormously important for my life path. 

But I can't do everything. I can't tour nine months out of the year with enough time to do the enormity of what I'm setting out to do."

He then goes on to detail the 1999 song "Aliens Exist":

"It's weird that people remember that song. It's, like, an eighth album track from, like, 20 years ago [1999's 'Enema of the State']. 

The very last line of that song references this urban legend in UFO folklore called Majestic 12, these documents that got leaked in the '80s that described an entire organization of top-level scientists, military people and intelligence officials that manage the information of this phenomenon. I put the name in that song, and the irony now is that I'm dealing with people from the modern version of whatever that group is called. It's a big deal."
