The Earth itself is 4.5 billion years old. Nonetheless, the six million years humans have been on Earth has allowed them to evolve, build tools, create civilizations, adapt to their environment, and become the humans we are today. It is hard to think about a time when humans were not on the Earth, but there indeed was a time.
Aldebaran currently has a diameter of around 61 million kilometers / 37.9 million miles, and a radius of about 30.7 million kilometers / 19 million miles. It is thus around 44 times bigger than our sun. Though it is much bigger than our sun, it has only 1.7 solar masses. Thus it is just 17% more massive than the sun.

Scientists have researched and estimated that our Earth is around 4.5 billion years old. Earth formed at around the same time as the rest of our Solar System. Earth revolves around the Sun once every 365.25 days – this is known as one Earth year. In one year, Earth rotates like a spinning ball about 366.25 times – they are known as Earth days.
The Earth is estimated to be 4.54 billion years old, so the Universe itself is, on average, around three times older than our Earth but only if the Universe is indeed 13.8 billion years old. Our galaxy, the Milky Way, might be a better comparison, as it is 13.51 billion years old.
