Aliens/Intelligant Life forms, do they exist?

2. Who is "they" and who is "us". Some organisms on Earth did not come from non-life on our Earth - they came from outerspace. Humans posess a collection of life that came from outspace to Earth via meteors.

There is no evidence for this.

3. "trillions" of planets? Who provided you with this number?

I think it was obvious that he was just implying a large, not exact, number.

4. You say you can't believe not another planet has remotely our conditions. In fact scientists have identified MANY planets that have our same make-up.

No terrestrial planets outside our solar system have been found yet.

Simply put the 100% meaning of life is to pass on your genes.

Science can pass no such value judgement. That may be a generalized observation of gene function, but "meaning" is something else.

Absolutely positively without any doubt whatsover, every single species and every single factor, adaptation, ability, quality etc... evolved for the sole purpose of breeding.

No scientist possesses such certainty. Also, evolution does not happen with intent (or "purpose" as you put it). Gene pool changes can occur for reasons other than better breeding. Differential success at breeding can be linked to each change perhaps.

You have eyes to see your mates...

You're stretching the point way too far.

I am trained in biology to the highest degree possible.

Such a state is not possible. Even the top biologists in the world have more they can learn from others about certain aspects of biology (at some level of expertise, one begins to specialize and become less familiar with other aspects).

You exactly answered yourself. HomoSapiens who were able to use tools

Essentially, all Homo sapiens were tool-users.

Abslolutely every single factor and motivation is to pass on your genes. It is not ones individual choice - it is a preditermined requirement of being ALIVE.

Passing on genes is certainly a big factor...but not absolute.
What do you say of those people who choose not to breed?

there are such speculations...e.g., life forming in the cores of comets (heated via radioactive decay, the cores would provide shelter from space, a source of liquid water, a source of organic compounds in close contact, etc.)

Yeah, but intellegent life ?! That's just out there...

There is no intelligent life out there.
I know because an alien once told me
