Japhia888 said:It is hard to call it mere coincidence that all the factors to produce conditions for advanced life are directly aligned with the conditions that make it possible to observe the universe. It would take a species as advanced as man to understand and measure the universe,and a galaxy, solar system and planet that is perfectly designed for mankind to develop!
That's like saying the time signature "11:11" is a miracle when you throw a glance at the clock for every one of the 1,440 possible combinations throughout a day.
One of the characteristics i find in many conventional Christian minds is the failure to grasp the actual cosmological scale and context that underlie our existence. Assuming that you are not a geocentrist, your observation still seems too focused on this:
This is not, by far, the only possible combination of "a star & a planet" for a life-sustaining environment we can conceive of. Cap'n Andromeda has already provided you with technical details; i would like to add some more numerical and pictorial references.
This is how our galaxy looks like from within. From the outside, it would look probably like this:
Our galaxy spans 100,000 light-years in diameter (i.e. it takes 100,000 years to get from one end to the other at the speed of light), containing 150 star clusters, 300+ billion stars in total. The largest known galaxies (the ellipticals such as Type-CD and Type-BC galaxies) can have diameters of more than 6,000,000 light-years and are about 100 times massive than ours, containing up to 100,000,000,000,000 (100 trillion) stars.
Out of typically up to 50 galaxies per each, gravity forms galaxy clusters:
Our galaxy group is structured like this:
Out of up to several thousand galaxy clusters per each, larger structures called superclusters have been formed, not by gravity but by the very expansion of the universe (note also how they are not uniformly distributed; wouldn't an "Intelligent Designer" have distributed them uniformly?).
From a yet larger perspective, we detect galaxy filaments, the largest known structure in the universe:
"Mpc/h" stands for "megaparsecs" and the "Hubble constant" (the rate of the expansion of the universe). 1 parsec is about 31 trillion kilometres (19 trillion miles) or about 3.26 light-years. So, the small range drawn in the pic represents 31.25 million times 1 parsec with the parameter reflecting the Hubble constant.
The exact total number of stars in our universe is of course hard to figure out, but it's estimated to be at least 1,000,000,000,000,000,000,000,000 or 1 yotta.
In the following video, Carl Sagan is going to calculate the possible number of civilisations within our Milky Way galaxy alone using the Drake equation (his data may be a bit old, but the overall scale of the result is still closely relevant):
I remind you this is within our Milky Way galaxy alone. How many galaxies are there in the observable part of this universe? At least 170 billion. And this is excluding countless other possible universes, if
1) the Big Crunch scenario is to occur (whereby the natural cosmological creation is to repeat eternally through the cycle of the Big Bang and the Big Crunch)
and/or
2) the multiverse model is true.
Do you now see how your Creationist assumption ludicrously leaves out so many natural possibilities for life in the entire Cosmos?
And just in case you haven't already looked into it: anthropic principle.
