Is there any truth in the legend about the birth of Siddhartha?

This [Life of the Buddha](http://www.buddhanet.net/e-learning/buddhism/lifebuddha/2lbud.htm) (also mentioned among Wikipedia's [Miracles of Gautama Buddha](https://en.wikipedia.org/wiki/Miracles_of_Gautama_Buddha)) says, > According to the legends about this birth, the baby began to walk seven steps forward and at each step a lotus flower appeared on the ground. Then, at the seventh stride, he stopped and with a noble voice shouted: > > > "I am chief of the world, Eldest am I in the world, Foremost am I in the world. This is the last birth. There is now no more coming to be." However I feel like the legend is far-fetched from the truth. Any comments or alternative views are very welcome.
