Vedic Devta's Planet
As per the wikipedia data which they have taken as per Indian Vedas and other scriptures of importance (like Srimad Bhagwat) one year of demigod is equal to 360 human years. That is if we consider that Devtas or demigods live on a planet, their time is 360 times slower than that of ours. Now as per Gravitational Time Dilation, time on a planet is directly proportional to its distance from source of gravity G pulling it (like in our case Sun is pulling Earth) we can say that the distance from some source of gravity G and that planet must be 360 times less than that of distance between G and Earth, that is they are closer to G. (That also means that clock ticks slower when near to gravitational source G.)
On a serious note to find an intelligent life form first we need to find this source of gravity G around which we and that planet will be revolving. Then we need to focus on planets in space which have distance from G around 1/360 times of distance between G and Earth.
