As far as I’m aware, my consciousness doesn’t have a birthday. I’ve probably been around as long as the rest of existence has. And if that’s true, my consciousness is trillions upon trillions of years old
.... oh, you meant my physical birth. Physically speaking, my body was formed sometime around February of 1990. I know this, because I did the math and traced my actual conception back to February.
BUIUUT, the particles, molecules and atoms that make up my body today where probably already around long before they came together to create this form I’m in now. So.... again, I’ve probably been around since the very existence of the universe.
