Has anyone ever tried to explain as to why our earth is the only planet in our Galaxy that can support life in such a perfect manner.......?

The story of creation explains life on Earth.If there is life on other planets isn't it odd that they aren't mentioned?

It's easy to demand proof that there's no life elsewhere in the universe.

Idk but prolly

Yes and it is the only 1 we are aware of there can be more

There is no proof our planet is the only one with life.

It supports life as we know it because life as we know it evolved to fit this environment.

If we had evolved on Mars, the Earth would be deadly to us.

That is quite an assumption, there are likely trillions of planets in our galaxy. We do not yet have the technology to find life on any planet outside of our solar system, nor has life on other planets or "moons" within our solar system been ruled out yet.

no explanation is possible, since the underlying premise is false.

we don't know if there is life on other planets. we don't know that there isn't.

Yes.

Yes, however it's an unwarranted assumption that it is the only planet which can support life.

We don't know if it's the only one... And, you make it sound like Earth was sculpted for life - when, in fact, it's life that adapted to Earth's characteristics...

Very few have tried without preaching.

Those who preach usually ignore:

Bacteriophages

Pathogenic viruses

Pathogenic bacteria

Pathogenic parasites

Mutagenic substances in the environment

Mutagenic solar radiation

Spontaneous carcinomas

Congenital birth defects

Genetic defects

Venomous animals

Poisonous plants

Volcanos

Earthquakes

Storms

etc.
