Somebody online is trying to tell me about a dream that she supposedly had during an extended fainting spell. Is it even possible to have REM when you faint, or is fainting like being uder anesthesia where you don't have any dreams?


Also, I'm not asking about hallucinations or other weird things that people sometimes see before they faint. I am asking if it is possible to have actual deams.

Evolutionists and Biologists.?
Abiogenesis and Evolution?

First law of Thermodynamics: If matter can never be created or destroyed then how did we get here?

And for the evolutionists:

What about?

Cosmic Evolution: Time, Space and Matter have to come into existance. You can't be any place and be out of time. You can have anyone of these without the other two.

Chemical Evolution:Where did we get other elements? Fusion can't be the answer because you can't get past iron with fusion

Stellar Evolution: Stars? We have never seen them form? So how did they? No one has ever proven the formation of one star?

Orgainc Evolution: Life getting started, this would have to result from the non-living

Macro Evolution: No one has ever seen a dog make a nondog. Sure you get variations but it is still a dog.

Micro Evolution: This is the only one that is scientific and it only shows variations within the kinds.

First five are purely religous:

And some more about the Big Bang:

So from a state of nothingness everything exploded into nothing?

So we all came from a dot and the dot came from nothing? That's science?

Who made matter? Just call evolution a religion like Christianity? So why do I have to pay for your religion to be taught in the schools?

The Conservation of Angular Momentum:

Should spin in same direction:

How come two planets spin backwards 8 of 91 moons are backwards? Problem for the Big Bang? I think so....

Second Law of Thermodynamics:

Order to Chaos.

Energy can't help because there would have been nothing to channel it. The japanese came Pearl Harbor some energy but did it help them? No.

Ask questions and I'll keep going.

Are people's beliefs based on genetics?
I wrack my brain, trying to figure out how so many Christians can reason the answers they reason.

Having been de-converted, I understand what a Christian believes. But there's a big hole somewhere - like this galactic bell-curve that just prohibits any measure of sound reason.

It's like a scary movie - a Twilight Zone where everyone around you is kind of insane.... Not a lot, they can speak English and drive and shop... But really!

It is astounding how much of the essence of the meanings of so many of these questions Christians completely miss!

If anyone knows of a genetic component that would correlate religious belief or faith with an inability to reason properly, I would love to hear from you.

Likewise, in psychology. I realize that many Christians have been indoctrinated since childhood and that this type of early predisposition to bypass reason can galvanize into a reality/delusion complex where the "victim's" ability to critically investigate their beief, dies.

Suppose that the wolves on Isle Royale die off because of disease or genetic defects from inbreeding.
Should we (a) intervene and import new wolves to help control the moose population or (b) let the moose population grow until it exceeds its carrying capacity and suffers another population crash? Explain your reasoning.
