what do you believe is true even though you cannot prove it?

I believe in rebirth. There have been evidence documenting this but no one can say it has been fully accepted.

I believe in God even I can't prove how he created the Earth and how he was created.

Aristotle held that any logical argument could be reduced to two premises and a conclusion. Take for example, "Socrates is mortal, since all men are mortal." Likewise, since life exists on one planet of our solar system and there could be so many solar systems like ours therefore, it is logical to assume that there could be life on other solar system as well. Life on this planet earth is not without a purpose. What it does? It is there to control the chaotic conditions on our planet earth. The life on this planet is the sensory organ of the universe. It conveys to the environment the temperature, humidity, etc. The trees and plants invite rains as and when it is needed. Due to life, the seasons appear with clock like regularity. If we see, the conditions on other planets of our solar system are far more chaotic. The conditions there are hostile and not at all friendly to life. May be life will eventually emerge on those planets as well.

I believe in God. I am not inteligent and educated enough to profe and argue about this matter. but most of the time or every minute I realise the love and protection of God.

For many, the case is like that only. We believe. That is all. We cannot prove. Here the nature exists. As we know, millions of millions of years have passed after the emergence of the universe/earth and the planets. We, through our thoughts and calculations we have reached certain conclusions and opinions. Basically, these conclusions and opinions are only certain calculations and not necessary that it should be like that. It can be applicable to rebirth, aliens, and in the case of God also. There is no proof. Still we believes. That is the power of faith and belief. Take the examples of the people who lived about 100 years back, and think of about 1000 years before, how people lived. They have their own thoughs and faiths. It is far different from that of today. When we talk about all these, there are justifications. But in reality, what?? All knows, but no one know!! We just follows and what else can we do? We say that we are having re-birth. And can't we say that this birth itself is not a re-birth? We can stop this topic here, because we are so small to discuss on this and it is never ending. Regards, Thank-s

I also believe in aliens or life on other planet as you said it is really impossible that we are the only human or life in this vast universe but proving such thing is really one of the hardest part you might be address as crazy or something and you might end up in a mental hospital. I really hate those kind of people who limit their belief in life but I can't blame them is their way to live in peace so they really need to take action on people who want to destroy that. But still we cannot hide it forever in the near future other life will expose them selves to us and we might end up living together or having a planetary war. I hope not well if you believe in God then you already prove it. take a look at your self do you look like a monkey or something? we are not right so there is only one answer for that and that is our creator.
