About how many years of human existence passed before the world population reached 1 billion?

Bearing in mind that the first billion people was attained approximately by the 19th century (mid 1800 AC) and that the first "Homo Sapiens" is dated back some 200.000 years ago in the southern tip of Africa, we could establish that "Homo Sapiens" is about 199.800 years old. However, recently, and in the the paleontological excavations in Atapuerca (Spain) there have been discovered some vestiges and tools of the so called "Homo Antecessor", which date back to one million years.
So that should be the approximate answer to your question if we consider the "Homo Antecessor" as our most remote ancestor.
It took all of human existence up to 1804 before the world population reached its first billion. Before then, hunting and gathering societies never managed to pass a few million, with scarce food supplies and a nomadic lifestyle limiting growth. The agricultural revolution and the domestication of animals provided a stable food source necessary for population to start growing. Better nutrition and healthcare following the Industrial Revolution accelerated this growth to what it is now.

When will the earths population reach 7 billion people?
Right now its December of 2019. This question was asked in 2011 back when we were hitting 7 billion people. The World did not end in 2012. We should use the years 2020 and 2021 to prepare for a more crowded world that is to comein 2022 and 2023 when there is 8 billion people on the world. Its possible that we wont reach 9 billion people. The world could end before then from some disaster like Plauge or asteroid collision. But to answer the question 8 billion people looks like its really going to happen some time in 2022.
What shape does a population's growth curve most closely resemble?
A population's growth curve most closely resembles an "S" shaped curve, known as the logistic growth curve. Initially, the curve rises slowly as the population grows, followed by a period of rapid growth, before leveling off as the environment's carrying capacity is reached and growth stabilizes.
If population of some city is 54000 and it increase 5 percent per year than what is the population 2 years before?
To find the population 2 years before the current population of 54,000, we need to calculate the population growth over 2 years. Population after 2 years = 54,000 * (1 + 0.05)^2 = 54,000 * 1.1025 = 59,445 Therefore, the population two years before would be 54,000.
