Did someone born in 2000 exist in the ‘90s?
Troll gestation is 10 years, so yes, a Troll child born in 2000 was conceived in 1990.
The egg that would become them existed inside the mother, and if born within the first 9 months of 2000 they existed in some form (embryo, fetus) during 1999. Otherwise, no. Have you discussed your obsession with a shrink?
The '90's were from 1990 through 1999. How could someone who was born in the year 2000 exist in the 1990's?
Only as a "potential human being", in that the egg which was fertilised to become that human was within the mother at that time. In practical terms - no.
not if the mother got pregnant in March, or February of 2000, then the nine months, and the baby is born in November or December
Yės depending on when in 2k thėy wėre born they would've existed as a Fėtus or an Embryo of various sorts in the 90s.
no they didn't and how could they if they were born 10 years later
