The Universe is Huge
Spacecraft Voyager2 is now about 12,75 light-hours away from our earth and it took the spacecraft almost 33 years to cover that distance. The nearest known planet outside our solar system is more than 10 light-years away.
In 10-20 years time, Voyager2 will leave our solar system and go interstellar.
Even if we find a way to travel with the speed of light, it would still take years to go to the nearest stars and planets outside our own solar system. The vastness of space is beyond comprehension.
