12 years = 144 months = about 626 weeks = about 4383 days on average = about 105,190 hours on average = about 6,311,390 minutes on average = 378,683,424 seconds on average (not counting leap seconds)
1.0X 10^12 seconds (1 hour/3600 seconds)(1 day/24 hours)(1 year/365 days) = 31,709.8 years

Oh, dude, a human can live for like around 2.5 billion seconds in a full lifespan. But who's counting, right? Just make sure you're making the most of those seconds, like eating pizza and watching cat videos.
The International Astronomical Union definition of a second gives 31,557,600 seconds in a year. That makes 12 years = 378,691,200 seconds. And that is not counting the leap-second corrections that are made from time to time.
Earth is about 4.5 to 4.6 billion years old. The universe is about 13.7 billion years old.
