Obviously the dude was invested in alien lifeforms before Blink-182's breakout album, Enema of the State, but we didn't truly learn of Tom DeLonge's space craze until hearing "Aliens Exist" in 1999. The lyrics outline an abduction, the guitarist singing, "I am still the skeptic, yes you know me / Been best friends and will be till we die / I got an injection / Of fear from the abduction / My best friend thinks I'm just telling lies." Was this inspired by real events? Is the truth really out there? We may never know.
