Actually, we can't even confirm the existence of atoms, let alone subatomic particles. But when scientists conduct experiments, they come to the conclusion that the particles are indeed valid. The more discrete physics becomes, the more theoretical it is.
Lack of lab equipment, Cowan Reines proved the existence of the neutrino in 1956 but to do that they needed a nuclear reactor as a source of a neutrino flux
Walter Baade and Fritz Zwicky proposed the existence of the neutron star in 1934. Antony Hewish and Samuel Okoye discovered "an unusual source of high radio brightness temperature in the Crab Nebula" in 1965, which turned out to be the Crab Nebula neutron star.
Tau neutrino was created in 2000.
Electron neutrino was created in 1956.
Definatly not! A Neutron is a kind of Baryon (a type of Hadron) made up of the subatomic particles: Up quark, Down quark and Electrons. Now a Neutrino is different, there are three different types. There are Electron Neutrinoes, Muon Neutrinoes, and Tau Neutrinoes. Neutrinos are a type of Lepton, for every Neutrino there is a equivalent non-neutrino. For example, There is an Electron and an Electron Neutrino. So to conclude Neutrino does not mean Neutron, instead it is describing a type of Lepton. This should answer the Question.

To preserve the conservation of; energy, momentum, and angular momentum in beta plus decay. Without the neutrino there is a measurable difference between the energy, momentum, and angular momentum of the initial and final particle. The neutrino rectifies this difference and it's existence was actually postulated before it was ever discovered!
The existence of wormholes has not been confirmed.
An antielectron neutrino is an antileptonic elementary particle - the antiparticle of an electron neutrino.
An antimuon neutrino is an antileptonic elementary particle which is the antiparticle of a muon neutrino.
No one has ever confirmed the existence of black tigers. They have been reported and rumored but never confirmed as existing.
Muon neutrino was created in 1962.
Tau neutrino was created in 2000.
Electron neutrino was created in 1956.
Because for the last 30 years scientistshave confirmed the existence of mantle plumes.Visual evidence.
