Okay yesterday around twelve at night my Dad, Mum, and I went out side to watch the meteor shower. We looked east and we saw what I guess was a star but it kept on changing colours? They were red, green, white, yellow, blue, and orange. I know it wasn't a plane because it wasn't moving. It just stayed in the same place. It was bright though and it didn't fade. So, that rules out meteor, comet, gamma ray burst, planet and as far as I know stars don't change colour they twinkle. Both my parents saw it.

are they not referring to such things as the observed changes in populations of organisms over time? And are not such changes referred to as microevolution, which as far as I understand do not in any way contradict the creationist view that God created the earth 6,000 years ago and began the human race through Adam and Eve....but is there an aspect of what is referred to as the 'fact of evolution' (not the overall theory of evolution) that contradicts the general creationist viewpoint (or a Biblical description of Creation)? If so, what?

Will you help me with this geometry question, please?
Thank you a bunch.
And show/explain how to get the result?
