1000000000/3600 = 10000000/36 = 2500000/9 hours
2500000/9 hours = 2500000/(9x24) = 11574.07407 days
11574.07407 days = 11574.07407/365 = 31.70979197 years (assuming 365 days in a year)
1 billion minutes ago was the year 110 . 1 billion minutes later will be the year 3913 .
One billion seconds ago is roughly the equivalent of 31.7 years ago, using the US definition of one billion. One billion is one thousand millions.

The Sun was born about 4.6 billion years ago as a result of the gravitational collapse of a region within a large molecular cloud. This event marked the beginning of the Solar System's formation.
Sciences say that the sun was formed 4,600,000 years ago
Earth did not exist 5 billion years ago. What would become Earth was part of a collapsing cloud of gas and dust that would eventually form the solar system. Earth itself formed about 4.55 billion years ago. When it first formed it was made largely of molten rock.
