I currently do not a religion or belief about how the world was made, what happens after death, etc. But I have been researching religion vs. evolution for a few months now, since a colleague of mine has been talking to me about her religion as a Jehovah Witness.

I have a few questions about both theories (evolution and religion)

RELIGION
Is there only one Bible?
Who wrote the Bible?
Who were the first humans?
Were they born?
What happens when we die?
When was the bible written?
Is there proof that God exists?
Why are there so many different religions?
Will human life exist forever?
Why did God make so many different human races?
If God exists, why are there so many bad things in the world? ie, Cancer.

EVOLUTION
What proof is there that evolution exists?
Where did it all begin?
What happens when we die?
Will life exist forever?
What is the oldest fossil found?
How do you know it is that old?

Any answers would be great!

That's all that's given in the ques. I tried assuming it as an isoceles but couldnt find too. Can anyone think of any idea please. Thank you!

In other words, where x=time in days in the linear regression equation, y=mx+b, and R-squared instructs us on the relationship of time and our values along our linear regression line, is there something similar to R-squared to measure the relationship of time and a simple moving average line?

Stated otherwise, I can do a simple R-squared analysis each day and find the linear regression trendline which is best explained by time (i.e., 125 days has a R-squared of .97 whereas a 27 day period has an R-squared value of .00). Is there a similar test I can perform, then, to determine which moving average model (time series) is best suited for my data each day?

Would the best moving average model actually be the converse of the best linear regression model? In other words, if a 27 day period has an R-squared value of 0, it's essentially a straight horizontal line. As a result, the prediction intervals at .05 etc., both above and below, also tend to be fixed horizontal lines.

let n be any positive integer.
n! = n(n-1)(n-2)(n-3)...3*2*1
then why not 0! = 0(0-1)(0-2)(0-3)...
in the series constants like 1,2,3,... will not come because these are > 0.
secondly 1! is also 1 will it not mean that 0! = 1! or 0 = 1

My understanding is that black holes have such a strong gravity that they suck everything remotely close to them in and now since about 2001 scientists have learned that black holes can move or float thru space, if this is true could everything in space eventually end as part of a black hole?
