Yes, I know there are studies that show that most of our very old memories are made up or fabrication from many sources.
Mine is of sitting on the driveway looking up at the bumper of a maroon car. When I asked my dad about it, he said he had a 1973 BMW Bavaria that was maroon around the time I was 3 years old. Looked just like the one below. Truly special to have that as my earliest memory....
