Yesterday's firework was a huge one, so we can still see it tonight,too. Or, yesterday I was sleeping and I didn't see the firework. So I can see it today. Do you understand these? No, I don't think so. (Big bang light flew far away leaving earth 13.2 billion years ago. )
They say big bang light became microwave, so now we can see it. They say the light happened 13.2 billion years ago and now it finally arrived at earth. Oh,no! It can't be! If they say that earth was here for 13.2 billion years, and the light of explosion which happened 13.2 billion years ago at the place where 13.2 billion light years away, arrived now, then they might be right. But 13.2 billion years ago, when big bang happened, earth must have been inside of big bang, even if the form of earth was different. As I wrote, big bang light flew far away leaving earth behind in a moment 300000 years after big bang happened. So I wonder how the big bang light could come to earth now. Well, suppose that we went to Firework Festival. We really enjoyed it. But even if the fireworks were wonderful and we want see them, just the ones which we have seen, again, everyone knows that we can't. Do kids say, " The fireworks were huge so we can see them today again. "? No, of course not. Even little kids don't.
Let's say people who live on Uranus could see the fireworks three hours after which rose on the far away earth using super telescope. Because Uranus was there when the fireworks rose. But it could be in a few hours, and after the fireworks were over, Uranus people couldn't see them again, either.400 years after it, North Star people could see it. But even if they enjoyed it for few hours, when it was over they couldn't see the same one again.
Anyway, just the same fireworks can't be seen again. Never. If you can fly faster than light, and you can catch up with the fireworks, then you can see them again. Otherwise no one can see the same ones again.
Well, earth had seen big bang light once, long time ago. Earth was just inside of big bang like someone was at firework festival.And big bang was over just like firework festival was over.
Earth had been traveling for 13.2 billion years long since then. Earth was once the form of gas, huge burning star, or it blew up and became gas again or so, and it traveled long way up here in universe. During that time, big bang light ( if it existed,) also had been traveling for much more long way. Last year's firework is still flying away by the speed of 300000 kilometers every second in the universe which is 1 light year away. ( 9500 billion kilometers away.) And big bang light is also flying away in the universe lighting up it, which is several thousand billion kilometers away by the speed of 300000 kilometers a second. ( When earth flies for 13 billion years, light will be at much far away place, because earth goes much slower than light. )
So, it means we human being can't see big bang light. If you say that big bang explosion was so huge that you can see it still now, or if you say that nobody saw big bang light so we can see it now, please go to see firework festival today, as I wrote. If you can say that only big bang light was so special, ( surely it was special,) that it didn't fly away and it stayed in universe just like sea water stays in the sea, then you can see the big bang light.

A s I wrote, after big bang, when universal fine weather happened, earth was there, too. Because earth was also born by big bang. Of course the form of earth was completely different, and the form must have been some kind of light, electron, or atom or so. Anyway, there must have been things which changed into the form of earth all together after some billion years later.That is to take photos of the light of universal fine weather ( cosmic background radiation ) means we see the light of earth itself which was once a part of big bang. We never can see ourselves. For example, we can't see yesterday's earth even if we set a telescope where earth was supposed to be. ( We can calculate the place. ) It is just like we cant take the picture of the past plane which we rode on even if we use a wonderful camera with special telescope lens and set it at the place where we flew 3 minutes ago , expecting to take a picture. Guess you focus your telescope on the place where earth was one month ago. Nobody think you can see the past earth.How about on the place where earth was million years ago? Of course there isn't earth there, because earth is here! Then, how about the place where earth was 4.5 billion years ago? At that time, earth was beginning to make the form using, gas, dust or so. Do you think we can see it because earth was not formed yet? I'm sure you say no. How about at the time when Milky Way was made 10 billion years ago? At that time the matter by which earth was made were so confused and mixed and nobody could see what they were. Then, do you think we could see them? We feel like being able to see them because they were so mysterious without any form. But the fact is we couldn't. Because Milky Way is now here.
Then, why could they take a picture of earth which was 13.2 billion years ago? What is the reason you can take a picture of earth which was 13.2 billion years ago? ( I tried to write reasons for it in Question 1. But I don't think the reasons are correct. ) Do you think big bang is so special that it doesn't obey the rules of physics? If so, don't you think it is not fair.
Conclusion
We can't see ourselves of past time. Even if it is big bang, we can't see. Oh, don't say you can see it in video tape!
# The other day I read a magazine called " NYUTON", and it said that big bang happened 13.7 billion years ago. The age of universe is different by books. By the latest information, the age might be 13.7 billion years. Even so, it is only a hypothesis as before. The other hypothesis that big bang didn't happen, still exist. The hypothesis is minority, though.
