Srini, you have some wrong info on the age of Brahma, read this.... http://www.encyclopediaofauthentichinduism.org/articles/48_the_exact_calculations.htm
The Bhagwatam says, %u201CBrahma%u2019s one day equals to 1,000 cycles of the four yugas (one cycle of four yugas is 4.32 million years). It is called one kalp. There are fourteen Manus in one kalp. For the same length of time there is the night of Brahma. This is called pralaya or kalp pralaya. At that time the earth planet and the sun along with three celestial abodes (bhu, bhuv and swah) enter into the transition period (and become uninhabited). During that period Brahma holds within himself all the beings of the material and the celestial worlds in a suspended state and sleeps. (The next day he again produces them and re-forms them as they were before.) In this way Brahma lives for two parardh (twice of 50 years). After that, there is a complete dissolution of the brahmand (the planetary system and its celestial abodes). This is called prakrit pralaya of the brahmand.%u201D (Bhag. 12/4/2 to 6)
one cycle of 4 yugas might be like a minute for him dude!!
