When did the Precambrian time begin?
The Precambrian is the informal name for the large expanse of time preceding the current Phanerozoic Eon. It began with the Earth's formation about 4.5 billion years ago and lasted until the advent of multicellular life about 542 million years ago. Overall the planetary environment was drastically different. Life appeared sometime late in the Precambrian, but it is not known when. The Precambrian "supereon" is divided into three eons: the Hadean, Archaean, and Proterozoic. Very little is known about the Precambrian, despite the fact that it comprises nearly 90% of the Earth's history. This is simply because Precambrian rocks are so old, and are either heavily metamorphosed, have been destroyed by erosion, or remain buried deep beneath Phanerozoic strata.
How long has man been around?
The human species (Homo Sapiens sapiens) started its existence between 110 000 and 50 000 years ago. Its development diverged from the apes about 5 million years ago. The earth has been capable of supporting life for about 3 billion years, and is expected to continue being able to support life for about 5 billion years in the future. If we viewed the period of being able to support life as 24 hours, then we are now about 9 o'clock in the morning, humans diverged from the apes about a minute ago and the human species started to exist 1-2 seconds ago. However life on the earth has only existed for about 1% of the time the earth has existed..

No. 1) the sun puts out a finite amount of energy. 2) the sun has a finite life-time. (about another 5 billion years).

What is the name of the supercontinent that existed over 5 billion years ago?
There was no supercontinent back then. Earth is about 4.6 billion years old. It did not exist 5 billion years ago.
Did earth form 50 billion years ago or 5?
Earth formed approximately 4.5 billion years ago, not 50 billion years ago or 5 billion years ago. This age estimate is based on radiometric dating of meteorites and rocks on Earth.

In 156 billion years will earth get scorched?
No. Earth will be scorched and possibly consume by the sun in about 5 billion years.
Will Earth be disintegrated in 2 billion years?
It is unlikely that Earth will be disintegrated in exactly 2 billion years. However, in about 5 billion years, the sun will expand into a red giant, potentially reaching Earth's orbit and causing the planet's destruction.
What is the earth's age?
It's generally agreed to be 4.5 billion years old, about one third of the Sun's age.
How old is the sun and when will it burn out?
the sun is 5 billion years old it will burn out in 5 billion more
Approximately what fraction of geologic time is represented by recorded history?
5 billion is equal to 5000 million or 5x109 years. As such:The fraction is 5000 / 5,000,000,000, which simplifies to:5 / 5,000,000 and again to 1 / 1,000,000.Therefore if Earth were 5 billion years old, and recorded history was 5000 years then recorded history would be one millionth of geological time.It may be worth noting that 5 billion years is somewhat of an over estimate for the age of the Earth and that the current best estimate for Earth's age is 4.567 Billion years old.
