atthestrokeoftwelve you have asserted that you have given a description of a Babylonian family - where did you get that description from, because it doesn't sound like anything an archeologist or historian would write. It reads like it is a piece of fantasy/fiction, but you are using it to support your argument that Easter is based on ancient traditions which began in the Neolithic period (which began 12,000 years ago, not 15,000).
The page you linked to is riddled with errors and unfounded statements, and is not something that can be used to support any suggestion that Easter has pagan roots. Briefly, I cannot recall any part of the legend of Ishtar where she is tied to a stake, East and oestrogen may sound similar but their etymologies are different, there is no evidence to suggest Ostara is connected in any way to bunnies or eggs, and I have no idea how the rock art at Roslin Glen is supposed to be supporting evidence for the other claims.
There is no evidence that Ostara has been celebrated at a goddess at any time in human history except for the last few decades.
I can also recommend Professor Ronald Hutton's book "Stations of the Sun", which is a fascinating journey through origins of many of our modern celebrations, including the Modern Pagan Sabbats.
