The "Big Bang" is impossible, for many reasons.
The idea that all matter came from nothing in an instant is insane. Light is simply a vibration of the dark matter. The Universe and all eternity is completely full of the subatomic particles that hold the planets and stars in their orbits. Light as a waveform, must inevitably alter its wavelength as it eventually peters out. The amazing thing is just how far the ripple in the ether called light can actually travel, relatively unaltered. That it will eventually get longer in wavelength is inevitable, it cannot go on the same for ever, even though we believe it has done so across millions of light years. That anyone should consider the inevitable slow up of the light wave to be the sole proof of creation of all matter in a microsecond just shows how stupid and brain-washable we are!
The sole alternative is that matter is infinite, and has always been present. Hard as this is for us to understand, this is the only other possibility. The more we look with stronger and stronger telescopes, the more this is seen to be true, the Universe is infinite, and the Earth is utterly unique, the product of Divine Creation.
