Why does time slow down/go faster with movement compared to another object.

The well known example that if you travel into space you'd gain let's say 5 years and people on earth 25 in the same time or so.

I just don't get it and I can't find any logic explanation.

For instance: Two twins who came to live exactly at the same moment in the year 2000 and both die on their 75th birthday at the same time. One travels into space, the other stays on earth. Earth-brother dies on earthyear 2075,space-brother dies in earthyear 3050 or so...

I know its Einstein's point but that just doesn't instantly make it correct to me.

try reading Brian Cox's "Why Does E=mc2? (And Why Should We Care?)". To understand this you will need at least 10 or 20 pages to set the stage before you can start to grasp special relativity.
