How old is our universe

The earth is around 6,000 years old. It cannot scientifically be 14 billion years old because earth is slowing down, this means it used to be going faster. This makes it so that carbondating cannot work because of the magnetic field and that if dinasaurs lived millions of years ago they wouldn't have gotten hit by an asteroid, they would've just flew off the earth.

13.8 billion years

Explanation:

In physical cosmology, the age of the universe is the time elapsed since the Big Bang. The current measurement of the age of the universe is around 13.8 billion.
