With the aborted babies added on to this (current number of people who ever lived is 107 billion), it's actually closer to 110-115 billion. But of course, nobody will ever add those children to the number. Yes, that many babies have been aborted during the entire course of the world. Just from 1973 when abortion became legal in America the world has aborted over 1.3 billion children. And that's just since 1973. Abortion in ye olden days wouldn't be like it is today, with drugs and sharp surgical instruments jammed up the womb, but forcibly causing miscarriages would also count as abortion. If I recall correctly, this is even mentioned in the Bible? Someone correct me if I'm wrong. So basically, abortion has been around as long as sin has been around.
