why aliens are more intellgent than us?

It been proved that when we go far from earth the clock ticks faster which means times goes away quickly like traveling in future

NASA has performed this experiment by putting a clock in rocket and one in there station,when the rocket launched it's been observed that seconds hand was ticking faster with respect to increase in distance from earth

In earth due to gravity we have a time at slow pace which help's us in development
but Living things which live on some far away planet aka aliens who may be on non-gravity surface may experience a quick flow of time .which means there development is quicker than us and more development means more advanced sophisticated tech and intelligence.
