The Big Bang theory, Google it.
Edit : OK, but what's "Answers" for then? Anyway, I agree it's a big question.
I'll let someone else have a go at it.
I would just point out that the Big Bang is reckoned to have been about
13.7 billion years ago. That number of 4.6 billion seems to relate to the
age of the solar system.
Perhaps that's what the question is meant to be about.

The dust and gas from the solar nebula took about 10-20 million years to form into the earth starting with the molten centre of the Earth which cooled down to form a crust that allowed water to begin to accumulate.
In one year there is 525 948.766 minutes.
So 525 948.766 x 10= 5259487660000000 minutes.
And 525 948.766 x 20= 10518975320000000 minutes.
So it took between the 5259487660000000 minutes and 10518975320000000 minutes to form the earth.
4.6 billion years ago was the early stages of the formation of the Earth and our solar system.
Answer: 46000000 mi. = 74,029,824 km
In 1610 Galileo was 46 years old!!!
The furthest distance from Mars would be when it is on the opposite side of the Sun from Earth, known as Mars' opposition. At this point, the distance between Mars and Earth can be around 401 million kilometers (249 million miles).
The answer is right there in your question. "Light year" is the distance that light travels through space in one year. In one year of time, light travels one light-year of distance through space. In 46 years of time, light travels 46 light-years of distance through space. It takes 364 years of time for light to travel 364 light-years of distance through space. Now, to return to your question: For light to travel 600 light-years of distance through space, that would take 600 years of time.
Gasoline weights about 6.3 pounds per gallon. Each gallon of fuel results in 20 pounds of CO2, because carbon from the fuel combines with oxygen in the air. C12 + O16 + O16 = CO2. I fill my car once about once a week. Some people drive a lot more, and others a lot less, but I figure my car is probably close to average. The tank holds 15 gallons, so that is 15 x 20 = 300 pounds of CO2 per week. I drive about 50 weeks out of the year, so 50 * 300 = 15,000 pounds of CO2. That is about 7.5 tons per vehicle per year. Humans emit a little over 30 billion tons of CO2 per year altogether. Americans burn 375 million gallons of gas a day, emitting about 1.4 billion tons of CO2 per year. If we divide that by 7.5 we get 182 million vehicles, pretty close to one car for every two Americans. The math checks out reasonably well.
