We need to pick a population number based on our ability to confirm reincarnation rates, unfortunately that's not very long ago. 600 million in 1700 CE and 990 million in 1800 CE.
1) If we go with the 600 million with the conservative end of the reincarnation rate estimate of 10 years.
This means we are reincarnating 5 times faster now than in 1700 and there should be approximately 3 billion people living (does not include those waiting to be born).
2) If we go with the 990 million and the liberal end of the reincarnation rate estimate of 12 years we are saying people are reincarnating 6 times faster now than in 1800. Our result would be 5.94 billion people living.
3) Therefore, our estimate spectrum is between 3 billion and roughly 6 billion people and that is incorrect!
There are around 7.5 billion people in the world today.
The concept of reincarnation as presented by eastern religions does
not presume infinite reincarnation, and certainly does not presume reincarnation both infinitely back in time as well as infinitely into the future.
The idea is that a sentient being comes to life. That sentient being has then entered into the cycle of birth-life-death-birth-life-death....
But not infinitely.
The cycle continues until the sentient being finally becomes enlightened, at which point the cycle for that sentient being is broken >>> reincarnation for that sentient being ends.
So...

Thus... "we" do not need sentient beings to come from some other place (planet, solar system, galaxy, universe, dimension). This doesn't mean the sentient beings could not have come from somewhere else. It is just atet that issue is irrelevant and ultimately neither adds nor subtracts from the system.
Earth has had more than enough sentient beings to account for all the humans on planet earth. Even if one wants to limit time to the short scale that some Christians choose to believe, that short time (6000+ years) has seen the living-dying-birth-living-dying...etc of more than enough sentient beings to account for all the humans presently on planet earth.
And if one takes longer time line, i.e. the millions of years that life has actually been on earth... again there have been more than enough sentient beings to account for the present number of humans (and other sentient beings) presently on earth.
etc.
