Islam is really plausible in everything.First, islam gives a logical explanation to the creation of the world,as it shows that this great design-earth, land, water, plants,galaxies,etc-was done by a great creator.This explanation is really plausible when knowing that the single cell is more complicated 5 times than a city like New york, while any person who is sane can't say New York was a matter of Coincidence.
Second, Islam recognizes all prophets -Noah, Abraham, Moses, Jesus and Muhammad-which means that Islam admits that other religions are from God, showing the unity of the source and the goal.
Third, islam, christianity and judism share the same principles except that it differs from christianity in refusing the concept of crucification and jesus's divinity- which is truely illogic,how can a god be killed and tortured by his weak slaves and is there another way for forgiveness rather than killing your son?!! and differs from Judism in refusing their stories about prophets (carrying a sexual taste) and refusing some of their provisions.
fourth, Qur'an carried great scietific breakthroughs inside it proving that it's from God
For example,
1.Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. Will they not then believe?(21/30): the great explosion theory
2.And We have set on the earth mountains standing firm, lest it should shake with them, and We have made therein broad highways (between mountains) for them to pass through: that they may receive Guidance.(21/31): it was also proven by modern science that mountains keep the stability of earth.
3.He has subjected the sun and the moon (to his Law)! Each one runs (its course) for a term appointed.(13/2)
4.He has created the heavens and the earth with the truth; He makes the night cover the day and makes the day overtake the night, and He has made the sun and the moon subservient; each one runs on to an assigned term; now surely He is the Mighty, the great Forgiver(39/5)>>>actually the word in arabic is encircle the night over the day and the day over the night, so if the move in a circle each one running after the other, so the earth must be circular
there are many other sceitific findings in quran , I hope you find them logical
