Genesis 4 tells us that Eve gave birth to Cain, and later Abel. When they are (presumably) young men, Cain murders Abel. It is shortly after this that he is cursed by god and expresses concern that he might be killed by "whoever finds" him. Later in that chapter, Eve gives birth to Seth, whom Adam says was granted him the place of Abel.
Chapter 5 tells us that Seth was born when Adam was 130 years old. If we grant that Adam and Eve were a "year old" when they were already fully adult, and that their rebellion and expulsion from Eden came relatively quickly (let's say five years) then Cain and Abel were born some 124 years before Seth. Eve would've been pumping out kids like a factory, and those kids would've been going at it like rabbits. Assuming few losses due to early death and lifespans in the hundreds of years, an early start to the sex lives of their children, and the breeding habits of gerbils, you'd probably have a few hundred or a few thousand people within a hundred years.
They'd be pretty tired, no doubt. I don't think Cain would need to worry about anyone trying to hurt him; they'd probably have enough trouble just walking.

"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
