We human have five senses to percieve this world. For example we see things by external eyes, and it is being percieved by the inner-mind-eye! This seeing experience can never be explained or transferred to a man who is born-blind!!
If it is the case with our-worldly-same-wave-length people, what is the case with other wordly people?
If some one has some other senses than our normal 5 senses, how could we understand or feel "that particular sense" through our other senses? ( in this case shall we also be not a blind?) And, even if some other creatures do live in this cosmos contemporarily, how could we come to know within our "mind-hold" and comprehensions?

It was mentioned in this book I just read. Is that what they eat? Are they actually a kind of roach or just a related bug? The book didn't give any specifics about them, just said there were a bunch in a house. Could cops use that as some kind of evidence or something?

My cousin was in my house the other day, and he found this spider in my toilet. He didn't know what to do about it so he stored it in some sort of a container. It was in there for a long time and it was on the sink so he kinda irritated the spider with water. He told me about it and we decided to set it free the next morning. And he was asking me if the spider actually got angry with us and if it will come back to my house to try and get 'revenge' or something. I didn't think much about it at first, but now I'm getting kinda scared. Is there any insect which is really able to make their way back to a place they have been to before?

some animals became giants from the single celled organisms that started this process, some stayed small. But some big ones are dumb and some small ones are really intelligent. So is it more amazing for a Giant animal that is not so smart to come from one cell or an amazingly smart lifeform coming from such a simple beginning?

Evolution is obviously false to any one with common sense.

I love to refute arguments for evolution. Here is one:

"If you don't believe in evolution and you except the fossil evidence, then you must realize that not every animal got here at the same time. Humans are not as old as dinosaurs. An elephant is not as old as bacteria, for instance.

If you believe in that, then it seems that at one moment, millions of years ago, there were no elephants, an then, the next moment (due to the abscence of evolution) there was an elephant. How long that moment takes is moot, because the point is the elephant did not come out of an uterus.

If you had a time machine and you were able to find out exactly when an elephant first appeared and you went back to that time, would you honestly expect to see an elephant just form?"

Isn't that a dumb, circular argument? What if the fossil evidence is wrong? I bet you have never thought about that. Besides this argument doesn't prove anything.

So I was looking through some old photo's last night and found a ton from when I was younger,and I seemed to have a different hair colour every year.

As a baby it was black.
Apparently I lost that and it grew back in blonde. (2-5)
That darkened to a coppery brown,which turned red. o.o;; (6-8)
That darkened to auburn and then chestnut brown. (9-12)
And since then it's been getting darker and darker,at 17 it's almost returned to black.

It's all natural so my question is what causes this,why does some people's hair darken and/or change colour as they get older?
