Krishn says, ‘On the end of this world all living beings are absorbed into me. I release them into the next world(kalp)’

Which means there is no new creation. Krishn tells the lifetime of the world order is of one Kalp. What is it? There are four cyclic time periods.

They are named SatYug, TretaYug, DwaparYug and and last is KaliYug. After KaliYug again SatYug and the cycle repeats.
The time durations are KaliYug 4,32,000 years.
DwaparYug which precedes KaliYug is double of the KaliYug that is 8,64,000 years.
TretaYug - 12,96,000 years
SatYug - 17,28,000 years.

These four time periods together make it 43,20,000 years. This cycle of four periods is called MahaYug.
71 MahaYug make one Manwantar which is 30,67,20,000 years.
14 such Manwantar make 1 day of Brahma which is known as one Kalp of 4,29,40,80,000 years.
That is the life of the world order is more than 4 billion years.

The destruction after 1 Kalp is called Pralay. (World Destruction) One night of Brahma is again 1 Kalp. By this measure Brahma lives 100 years. At end of this time period, even the kingdom of Brahma is destroyed. This is called as MahaPralay (Total Destruction). After Mahapralay, God alone remain in existence and everything else remain in micro state inside of God or in the belly of God.

This makes the life time of the whole universe is 858,408,000,000 which is about 860 billion years.

These time estimates are really huge but they are nothing compared to infinity. What to talk about human life? It is very very short and must be utilized properly to overcome death and sufferings forever by attaining eternal bliss.
