Why do Atheists misunderstand all abstract concepts ?

Mere blobs of flesh

1 Corinthians 2:14 — People who aren’t spiritual can’t receive these truths from God’s Spirit. It all sounds foolish to them and they can’t understand it, for only those who are spiritual can understand what the Spirit means.

So you attempt to advance your argument by disparaging the people who disagree with you.  Certainly it's possible to disparage someone honestly, but you can hardly be described as honest.  You are a blatant liar, and at some level you know that.  I'm a Ph.D. scientist, and you say that I "never fail at misunderstand [sic] any abstract concept."  You seem pretty sure of your position for a person who can't even write a proper English sentence.

Just about everything we have in language is nothing more than an idea, or vehicle, to try to convey those abstract concepts to each other.  As for fine tuning..... well this planet we live on is capable of supporting life.  But only 20 or 30 percent of it can sustain HUMAN life.  Doesn't sound very fine tuned to me.  Like Intelligent Design.... we have one tube for eating and breathing.  We are in constant danger of choking to death.  Doesn't sound so intelligent to me.  Try reading a real book.  Start with basic science and move onward from there.  Once you replace your ignorance with real knowledge, you might not sound so ridiculous.

We have always understood that humans had to evolve and work to survive on this planet. You must not have been listening on this point. The point you are making that we disagree with is that you say the earth was created by a supreme being just for us. We believe the earth formed randomly from matter left over from the big bang. And the earth evolved into a place that is able to support life. I think it is your understanding that is very limited.

fine tuned for humans, but 70% is uninhabitable by humans? you make me laugh with your trolling

That is one of the strangest explanations of "fine tuning" that I've ever heard, not to mention it does not address, in any way, the common usage of fine tuning nor does it reflect anything I've ever heard an atheist say about fine tuning.

Generally speaking, "fine tuning" refers to the set of constants that seem arbitrary and allow for this universe to exist in such a way that life could exist on this planet.  It's an abstract concept but with a little thought II'm sure you will catch on.

Their being blind and in darkness doesn't bear favourably on their being able to comprehend things.

Worse, the Atheists on R & S show themselves brute beasts. Just look at their sad answers!

Life on earth evolved spontaneously because conditions were favorable..not the other way around..

Most atheists have no problem at all understanding abstract concepts. Theists not only do not properly understand abstract concepts but in general are massively ignorant of science and virtually wholly devoid of rational thinking skills. In general, atheists are much more intelligent and much better educated than theists. 

We understand just fine.  We understand well enough to point out the holes in your concept and how your ideas are shaped by doctrinal needs, not by scientific data.
