Alpha Centauri-A,

It is only a concept about distance between two stars. which is invented by 4 Time year. therefore basic distance is 4 Time year into the photograph. and it is very easy and perfect for accept to brain. each that ect, which our brain accepts that they always right. or our brain always accept the truth. It is our a manufacturer fault. such as, you are reading “xyz” about distance of Central Milky way from the sun. which is 65 percent right. and it is knows you, 

but you will continuous read. But after the some time, you are reading "xy yz" distance of sun from the Central Milky way. which is 93 percent right. but you will read continuous. because these number are better than last number. So the brain is always accept to fact. But why our brain always accept to truth. because the Day and Night are a truth from trillion and trillion years. and our brain is doing accept to this truth from trillion and trillion years. So the truth is fact by the system of Day and Night.
