Well first of all - it's a matter of whether or not you believe 'God' did it, or it was a matter of evolution.
But putting religious issues aside.....
You say Earth is tiny...
Well actually Jupiter and Saturn are also tiny - even our Sun is tiny, compared to the whole Cosmos.
Our whole galaxy is tiny and insignificant, when compared to the vastness of the Universe - within our galaxy, Our Sun and whole planetary system is tiny and insignificant - and within any solar-system, any individual planet is only the tiniest fraction of the whole system.
Now compare Jupiter to Earth - Sure, Jupiter is far bigger - BUT....
The solid centre of Jupiter is only about 10% of the total Mass - this is overlaid with hydrogen that is compressed so densely, it is a metallic liquid - then the clouds are above that.
Before you even got to the depth of the liquid metallic hydrogen though, the pressure is so high that you'd be crushed - even the strongest submarines couldn't withstand the pressure.
If Jupiter was solid all the way through, then it would be far more massive than it is, and the surface gravity would be immense.
In short - even if it had oxygen it it's atmosphere (which it doesn't) a
soild planet the size of Jupiter would still be a no-go for humans to walk on it.
It's also too far from the Sun, and far too cold for us.....
For life as we know it to evolve, a planet has to fit into several specifications.
It needs to be the right distance from the star, so that water can exist as a liquid - it needs to be large enough to hold on to an atmosphere, yet not so large that it has crushing gravitational forces -The atmosphere need to be thick enough to protect us, but not so thick that we have an immense surface pressure....
And many more factors, but they are the main ones.
In our solar system, only Earth ticks all the right boxes.
We evolved here, because this is the only planet in this system where we could have evolved.
