1) Thanks for the "fanatics" keyword. It shows what your attitude 
actually is.

2) If you care to read what I wrote:

<quote>
Actually, our intelligent signal (radio signal) is more than 50-60 light 
years away, and all stars within a sphere of that radius centered on the 
earth have received a signal coming from us...
<end quote>

It is obvious that I was speaking about the sum of all radio 
transmissions coming from earth.

An automata scanning the nearby starts (20-30 light years is not very 
much in cosmic distance terms) will immediately detect that the sun that 
has benn quite silent in the radio frequencies for millions of years, 
suddenly (in the space of some dozens of years) gets brighter.

3) To your calculations:

3.A) You suppose an emitter of 2KW. GREAT!

The power of a typical FM radio station in the U.S. is 50-100 THOUSAND 
Watts, (see http://en.wikipedia.org/wiki/FM_broadcast_band) i.e. your 
calculations are wrong by a factor of 25 to 50 for each emitter. Then, 
how many FM stations do we have in the earth? How many TV stations in 
this planet? Let's say 10 thousand. We ignore all the other radio 
emissions from planes, ships, radio-amateurs,  radar, etc. So, now we 
have that you have missed

	A FACTOR OF 10 000 x 25 --> 250 000.

So, it is not 20 photons that arrive to E.T but 20 * 250 000, i.e. 5 
Millions photons.

OK?

3.B) Now you suppose a single telescope receiving the data. But in radio 
astronomy, you make interferometers, like the ALMA receiver that spans 
several kilometers in the Atacama desert in Chile. Aliens could make 
huge interferometers in space with a virtual radius of several hundred 
KILOMETERS!

4) You are ignoring the signals we have sent using the Arecibo telescope 
at certain directions. Those signals are stronger than the sun at the 
given frequency.

Look, I described several facts in my message and all I get are answers 
like yours: people that do not have an open mind but try at all costs 
(even the costs of rational thinking) to prove that UFOs are "nonsense" 
hallucinations whatever.

How could humans get a precise description of the Milky Way 7 THOUSAND 
years ago? With no scopes at all?

I gave the ISBN of the book. Read it, then try to understand. I am not 
an UFO expert but I have read enough serious books about the subject 
before having an opinion.

Just do the same and forget your prejudices.
