With NASA scientists claiming to have headed towards discovery of other Earth-like planets, existence of aliens on these planets is fast catching up as a belief among the Vaticans.

Kepler 452-b, estimated to be 1,400 light years (26million miles) away, is being perceived as a planet similar to Earth. Scientists estimated it to be having a rocky surface.

There is a sensation in the Vatican Observatory, which is a branch of the papacy. This branch is dedicated to the study of stars since 1582.

"I am open to the possibility of extraterrestrial life and have been for quite some time. I find no contradiction between Catholic theology and the belief in aliens. In the past that humans shouldn't put limits on God's creative freedom," said Rev. José Gabriel Funes, an astronomer who directs the Vatican Observatory.

However, he raised a question mark over the belief of the existence of an alien God. He stated that the discovery life does not necessarily imply that there could be another form of Jesus (God) present. He further stated that the incarnation of the son of God is a unique event.

The Vatican Observatory has a telescope at Mount Graham International Observatory at the University of Arizona, in the US.

The Catholic Church has also been questioning the theories pertaining to extraterrestrial life. There has been a conflict between religion and science.
