I've got a different view to most, having being raised by a star seed as a star child; which has been further explained to me by a lot of different people, all spiritual teachers / healers.
All of our souls come from any number of different planets and dimensions. Everyone on Earth is an old soul and has lived many thousands of lives. We wouldn't be here at this time otherwise.
The star seed label comes from, as it was explained to me, the DNA of the fetus being adjusted to allow a soul that vibrated at a higher frequency to inhabit it. The star child is the child of a star seed, whos DNA has been further altered.
In a lot of ways, I've been waiting for 'at home' tests that would analyse DNA, if only to confirm whether what I've been told is true... as far as an 'at home' test could make that distinction.
