Bingo now prove the Big Bang happened.
We can still pick up on the radiation caused by the big bang...
Oh boy

let me educate you on this as well.
1st law of thermo dynamics.
The law of conservation of mass & energy: matter(energy) cannot be created nor destroyed.
So I need to ask you where did the ENERGY come from ? where did the energy come from to power my laptop ? or the lights in my home ? or to spin this planet ? or to power the sun ? or move the stars throughout the universe ?
Human Antiquity an introduction to Physical Anthropology and Archaeology. Kenneth L. Fader and Michael Alan Park 2001 4th edition pages 44 & 45. Quote from the textbook.
"in the beginning all the energy was condensed into an inconceivably tiny speck the laws of Physics can't account for this"
This goes agains't the laws of physics,so they can't logically account for the energy.
So where did all the matter come from to form all we see ?
Let's go back to the textbook. " the tiny speck began to expand by 3 minutes atomic nuclei appeared" They can't tell us if the Big Bang took place 6 billion years ago or 13 billion years ago or 20 billion years ago so its constantly changing,yet they are gonna tell us what happened at the 3 minute mark

This doesn't make any sense what so ever. This is a religous belief it's not based on testable observable science.
I found this.
A letter signed by dozens of scientists that appeared in the New Scientist (Bucking the Big Bang,182(2448)20,May 22nd 2004) statements included.
"The Big Bang theory can't boast NO predictions that have been validated by observation. Claimed sucesses consist of retrospectively making observations fit by adding adjustable parameters."
Let's look at some of their adjustable parameters they added.
1. cosmic collisions are one of the magic wands which prop up the failed materialistic predictions.
Uranus is tilted over; Venus rotates the wrong direction; mars' atmosphere is too thin; Mercury is too dense; therefore,something collided with them to cause them not to fit the predictions !
The letter included statements such as :
The big bang relies on a groiwing number of never observed entities such as, inflation,dark matter,dark energy and can't survive without these fudge factors,in no other field of Physics would this continual recourse to new hypothetical factors be accepted,its only accepted because it's a religous belief not observable testable science.
Another proof thrown out is red-shifted starlight.
Possible causes include :
1. Stellar motion. assumes stars are speeding outward from the big bang.
other examples of causes of red-shifted starlight.
1. Second order Doppler effect.
a light source moving at right angles to an observer always appears red-shifted,implying the universe is in a circular motion not expanding.
2. Gravitation. The star's gravity or the gravity of a galaxy may lengthen the wavelenglenth of the starlight. Light could be speeding toward or away from the earth.
3. Photon Interaction. That light waves lose energy while traveling across space,reddening its light.
4. other hypotheses include: the slowing of light or galaxies spiraling toward earth may cause the apparent red-shift.
So redshift is not evidence of the big bang.
Now getting to your comment.
They claim MBR is leftover energy from the supposed big bang. they leave out alot of problems with this, for instance, without hypothetical inflation the big bang does not predict the smooth cosmic background radiation.
Yet inflation requires a density 20 times larger than the big bang's explanation of the origin of the light elements implies ! The MBR is going in different directions not one direction, I believe the stars are the source of the MBR.
Also if the big bang took place billions of years ago,by now all of the matter in space should be evenly distributed but it's not. Stars are found in tightly wound up galaies or balls. This is called the winding up dilemma. The universe is to tightly wound up to be old.
