Interstellar Travel Limits and the Improbability of Real-Time Alien Sightings

To the point

alien11152 argues that all alien sightings are fake by saying nothing travels faster than light, so even a civilization moving at 0.9999c would need enormous times to reach or observe Earth, making real-time detection or visitation from distances like 10,000 light-years or more highly unlikely.

Interstellar Travel Limits and the Improbability of Real-Time Alien Sightings

A user named alien11152 argues that all alien sightings are fake, claiming that nothing travels faster than light and even a civilization moving at 99.99% of c would face enormous travel times, so at distances like 10,000 light-years or more Earth would not appear habitable to distant beings, making detection or visitation unlikely and sightings effectively impossible or extremely improbable.
