This is not a matter of whether god is real or not, this is just simply a few reasons why any person with a brain should see that young earth is completely impossible.
1. A light year is the distance light travels in a single earth year. Some nearby stars are 4 light years or 20 light years away, but some stars and star clusters on the other side of the galaxy are as far as a 100,000 light years away. The center of the milky way galaxy is 26,000 light years away, and the andromeda is 2,538,000 light years away (2.5 million). What do these distances mean? They mean that the distance away from the object determines how long it takes for the light to get here, so it would take 2.5 million years for the light from andromeda to get here.
2. For creationism to be true, it would mean all radiometric and carbon dating methods must be completely false and not work. Even worse, it would mean that they are wrong but in a weird sort of organized fail, like for example even though t-rexs are "actually" 6,000 years old, somehow even though the radiometric dating method is inaccurate, somehow all the t-rex fossils somehow managed to date to between 66-67 million years ago. All of this would have to happen by accident and not just trex fossils, all australopithecus fossils would have to date between 2-4 billion years ago only and all by accident, all saber tooth cat fossils would only date 10,000 - 2 million years old again due to an accident. See how this doesn't make sense? CONTINUED>
Added (1). CONTINUED: If all the dating methods were false, the fossils which are supposedly "falsely dated" would be all over the place, they wouldn't show certain animals only existing in certain times. You would have 2,000 year old t-rex bones in one place, and 5 trillion year old t-rex fossils in the other.
3. The universe is expanding and humans can measure it. The big bang isn't made up out of nothing. There was lots of research put into it and the measurements point to 14 billion years.
Added (2). @Gregory, so in other words "who cares what reality says, god still did it".
Added (3). @TrevLev, well i assumed since it's yahoo answers people would automatically know that they should give their opinions and agree or disagree.
